spa3102 & CID

Hi,

I have configured my SPA3102 to handle CID on PSTN line. In our country the standard is ETSI FSK + V23. Everything is working fine - during a few calls or on first day. After that the 'Private caller' string is displayed on the phone, no caller id displayed on WEB information screen. If I switch off and on the device (SPA3102), the CID is displayed again during a few calls.

I use the latest firmware (5.1.10).

I hope, someone can help me.

Regards, kabelnet (Tamás Borlay)

Re: spa3102 & CID

Hi Tamás,

This is an interesting problem. Do you have another SPA3102 that works all of the time?

Did this SPA3102 display caller id properly before you upgraded its firmware?

Patrick

Re: spa3102 & CID

HI,

No, I have only one SPA3102. PSTN - Voip - Panasonic phone. Before that I used two phones - one with PAP2, other on PSTN.

There was the same problem before upgrade. I read somewhere on Internet, that the solution (to display CID) maybe the upgrade. I think it is not true, I changed the service subscriptions when the CID started to work. I was happy, but next day I get the 'Private caller' again. Then I found the 'reset technic' to restore the normal operation of service - but it is not comfortable. I want to found any solution. It seams, that there is problem only with CID, inbound and outbound is working fine, in both direction, without reset.

But it is not easy to get support in Hungary... I get the address of this forum from cisco.hu.

Re: spa3102 & CID

Hi Tamás,

Please do the following:

1. capture a syslog trace when caller id is working

2. capture a syslog trace when caller id is not working

3. save the SPA3102's configuration

4. send the two traces and the configuration to me at paborn at cisco.com

Re: spa3102 & CID

Hi Patric,

Should I register as Cisco partner to download syslog server, or there is any other way to get that program? Because I am not and will not Cisco partner....

Re: spa3102 & CID

Hi Tamás,

You can do any of the following:

  1. Contact me at paborn at cisco.com and I'll send you slogsrv.exe for use on a PC
  2. Use a free syslog utility available from the Internet
  3. Use the syslog daemon available on any UNIX / LINUX computer

Re: spa3102 & CID

Hi Patrick,

At the moment trace started there was no CID on phone. I called the SPA3102 with my mobil. The trace is trace_no_CID.txt, the status page is Linksys_SPA_Configuration_no_CID.html.

I switched off/on the device. I called it again with my mobil. The CID is displayed on phone. The trace is trace_OK.txt, the status page is Linksys_SPA_Configuration_OK.html.

I get the TP Parser error: 34 message during the trace, but it seams the server was working.

The difference, in case error:

FXO:Start CNDD
Calling:06213803497@127.0.0.1:5060
[1:0]AUD ALLOC CALL (port=16408)

[0:0]RTP Rx Up
CC:Ringback
[1:0]RTP Rx Dn
AUD:Play PSTN Tone 9
IDBG:sc-0

AUD:Stop PSTN Tone

If OK:

FXO:Stop CNDD
FXO:CNDD Name= Phone=06209370726

AUD:Stop PSTN Tone

Thats all. I hope you can say anything. Thank your help! Regards, Tamás

Re: spa3102 & CID

Hi Patrick,

I change the description of the problem. After switch off/on the CID is displayed. I make a call with my mobil. If I hook off the phone, make a talk, and hook on the phone, then after that the CID is not displayed anymore.

Attached documents:

I saved the configuration before the 1st call and after the 1st call. The trace contains the full trace of the 1st (good) call and the 2nd (no CID) call.

Re: spa3102 & CID

i have bought my spa3102 around 2 years back and till date i havent been able to get callerid working on it in the UAE, i have asked this question in almost all forums, even directly to linksys and it seems no1 has the answer to it and so i let it go thinking its not compatible in UAE untill the time when one person reported hsi callerid was working ocassionally leaving the spa to the default settings of bellcore but for me it hasnt even showed once and i have tried almost all possible way to get it running but it just wont for some reason and the main issue is even linksys wont help on it to get it working.

by using callerid converters etc in between the line and the spa, then it starts to show caller id so basically the hardware doesnt have any fault but its just the callerid standard isnt compatible with the device or its just the ring pattern and the time when caller id is sent and that time the device wont detect it due to some mis config so i would really appreciate it if some1 could finally get it sorted out.

Re: spa3102 & CID

Hi Bipin,

I'll check with my colleagues to determine if they've any suggestions for me to share with you.

Please send me your config so I can analyze for anomalies.

Re: spa3102 & CID

Hi Bipin,

I checked with my colleagues and was informed that UAE uses the same regional settings as the UK.

I opened up the SPA9000 Setup Wizard's UK.xml file and compared to your config and see that they are significantly different.

Please try the following changes to see if your caller id performance improves:

Voice tab > Regional tab > Miscellaneous:

FXS Port Impedance: 270+750||150nF

FXS Port Input Gain: -3

FXS Output Gain:  -3

Caller ID Method: ETSI FSK With PR(UK)

Caller ID FSK Standard: v.23

Patrick

Re: spa3102 & CID

i tried, doesnt work and i think the PSTN port impedance is 600 and the FXS port impedance doesnt matter much, the calelr id method and standard u told me, i tried it, doesnt work at all, actually i have tried any and every combination of the things in both the lists but it just doesnt work so i assumed mayb its just not compatible but all of my dialup modem detect it very easily.

i even tried getting a universal caller id converter and it used to convert from existing to DTMF which spa3102 could detect easily but it never told me what was the actual standard used in the PSTN which still remains a mystery.

r there any test tools to detect the caller id standard on the line using the modem or any other hardware?

Cisco Employee

Re: spa3102 & CID

Hi Bipin,

The impedance is important for proper caller id decoding. Please contact the provider of your PSTN line and ask them what standard they follow when delivering caller id. Better yet, locate their technical resources on the Internet and locate the caller id specification. Once identified, the SPA3102 can be appropriately configured.

Patrick

Re: spa3102 & CID

the pstn line provider has the following info posted on their site

ETSI ES 201 235-3      
Access and terminals (AT) specification of Dual –Tone Multi Frequency (DTMF) Transmitters and receivers; Part 3 Receivers.

thats the only info available and the impedance is 600, the reason i say this is because i have read on voxilla by other users also.

New Member

Re: spa3102 & CID

although the pstn line providers site says DTMF but i contacted the company and they said they use FSK and thats the only info i got out of them and i also use a LG Nortel phone and on it it says caller id = FSK (Type 1) and it works perfectly fine with my line in decoding caller id.

mayb some1 more experienced in caller id standards can explain what exactly is the standard when a device says FSK type 1 compatible.

Re: spa3102 & CID

Hi Tamás,

Looking over your configuration, I see that Voice tab > PSTN Line tab > FXO Timer Values (sec) > PSTN Ring Thru Delay: 1

This setting is extremely short for the device to properly receive caller id.

Please change it to 5 and test a few times. If caller id shows every time, even after use, then reduce to 4 and test again, reducing until caller id fails.

Once caller id fails, change the setting to 1 second more than when it failed and all should be good.

Please test this and let me know.

Regards,

Patrick

Re: spa3102 & CID

Hi Patrick,

It seams, that it has no effect to the problem. I tried several values (1-9) with and without switch off/on the device, but the result was the same as the original situation: after the reset the first received call was fine but the others resulted 'Private caller' only.

The Ring thru delay = 1 value was the original one, I did not change it during setup.

Re: spa3102 & CID

Hi Tamás,

Thanks for testing this for me.

I am out of ideas for now and have requested support from Engineering.

Do you have any way to verify that caller id is always presented on your PSTN line please? Perhaps connect an analog phone that can display caller id and make several calls and verify that caller id is always displayed.

Regards,

Patrick

Re: spa3102 & CID

hi,

yes the caller id works everytime on my phone connected to the PSTN line, i use a LG Nortel phone as well as a Siemens Gigaset and my 3Com dialup modem also displays caller id everytime.

my PSTN provider is called Etisalat and i think they use telcordia servers for PSTN and they use FSK caller id standard and after lot of testing, the spa3102 doesnt show any sign of polarity reversal when sending caller id.

when the PSTN wire is connected to the FXO port then the voltage is shown as -49 which i dont think should be an issue as the spa works with negative voltage also. Please let me know if those tip ring voltage etc such settings affect it or no.

Re: spa3102 & CID

Hi Patrick,

Before SPA3102 my Panasonic DECT phone was connected directly to PSTN. It displayed always the caller id (if it was enabled on the caller side). I assigned different sound to different callers, etc. And it was working.

Now it is working after a rest, to the end of first call. I suppose, that something is not restored to basic status, therefore next time the caller ID is missing.

I asked my telecom about CID. The answer was 'ETSI FSK with Ringing Pulse Altering Signal, V23'. The tone parameters were get from http://www.3amsystems.com/wireline/tone-search.htm .

I hope, there will be any solution.

Re: spa3102 & CID

Hi Tamás,

"Now it is working after a rest, to the end of first call. I suppose, that something is not restored to basic status, therefore next time the caller ID is missing."

Are you saying that your Panasonic DECT phone only displays caller id for the first call?

What country is the SPA3102 located in? Who is the PSTN provider please?

Regards,

Patrick

Re: spa3102 & CID

Hi Patrick,

Sorry, if I was not clear.

Panasonic displays the CID if it is connected directly to PSTN. Everytime.

It displays the CID only until the end of first call, if it is connected to SPA3102.

My country is Hungary, telecom is T-Home.

Re: spa3102 & CID

Hi Tamás,

Thanks for the clarification.

While analyzing your log files, Engineering noticed log entries indicating firmware versions 3.36 and 5.1.10.

Can you confirm:

  • Which version are you currently using?
  • Are you experiencing caller id issues with both versions of firmware?

Regards,

Patrick

-----------

New Member

Re: spa3102 & CID

Hi Patrick,

The 3.36 was the original firmware with which I bought the device.

When I detected the CID problem, I downloaded and installed the latest available firmware. This was 5.1.10. The CID problem was detected in both versions.

Now I use 5.1.10.

Re: spa3102 & CID

Hi Tamás,

Thanks for the information.

I escalated the issue to Engineering and they feel that the caller id problems could be a result of conflicting configuration parameters.

Can you please try the following:

Save your SPA3102's configuration

Factory reset the SPA3102

Configure the least parameters in order to get the SPA3102 working

Make 5 inbound calls and verify that caller id works on both the SPA3102 and on an analog phone

Assuming that caller id is now received each time that information is displayed on an analog phone, make one change at a time and then test with 5 inbound calls, until you are done, or the SPA3102 stops receiving caller id.

Please let me know of your progress.

Regards,

Patrick

Re: spa3102 & CID

Hi Patrick,

Today morning I made the 'big test':

1. Factory reset (73738), set WAN, LAN, allow remote management
2. I added Voip proxy and login. It registered successfully.
3. First test: 1st call: CID OK, 2nd call NO CID!!!!!

After that, I think no other test is needed. But I restored the original parameters step by step, and tested the CID after the steps.

4. Restored dial plan (it has no effect to incoming calls) and caller id method ETSK FSK, V23.
5. Reset, test (I started the syslog server now. Sorry.). The same problem: CID is displayed at the 1st call only.
6. Restored the line parameters (220+820/120nF), disconnect tone and other tones at regional settings.
7. Reset, test, same problem.
8. I restored the original configuration.

Any suggestion?

Regards, Tamás

(I attached the log of the test.)

Cisco Employee

Re: spa3102 & CID

Hi Tamás,

Thanks for testing so thoroughly. For completeness, can you please save the device's configuration again for me.

Once I have your configuration, I'll send the syslog and current configuration to Escalation Engineering to see if they have any suggestions.

Regards,

Patrick
