Solved: CME - SIP Trunk - Can't get incoming calls.

infologic · ‎09-17-2010

Hello

I am having some problems trying to receive calls on my UCME using SIP trunk. I am using a 2801 with UCME and managed to "successfuly" configure it. The fact is that I can place calls from my phone but when I receive calls nothing happens and the caller phone gets a "network busy" or "network failed" notification. I use a simple configuration where :

internet access <--> 2801 <--> Switch <--> 7912 phone

My 2801 configuration is as follows :

version 15.1

voice service voip
gcid
no cti shutdown
callmonitor
allow-connections h323 to h323
allow-connections h323 to sip

where 0975172273 is my public SIP phone number and 404 is the 7912 extension.

The SIP parameters appear to be ok given that the account is registered.

When I place and outgoing call, the called phoned show the 0975xxxxxx number so I guess it's still good.

When I get an incoming call

I guess the 403 Forbidden error is the problem but I don't see how to fix it. Any help is welcomed

Thanks.

Probably the inbound call is matching dial-peer 0, so the translation doesn't take effect, so the gateway doesn't know how to route the call.

For the original poster, use this to force the inbound dial-peer match:

dial-peer voice 1 voip

incoming called-number .

Hello,

Can you kindly check the below link:

Thank you I checked that link and fixed the ip address trusted list which is now :

Cisco2801#show ip address trusted list
IP Address Trusted Authentication
Administration State: UP
Operation State: UP

IP Address Trusted Call Block Cause: call-reject (21)

VoIP Dial-peer IPv4 Session Targets:
Peer Tag Oper State Session Target
-------- ---------- --------------

IP Address Trusted List:
ipv4 0.0.0.0 0.0.0.0

But I still have the same problem, incoming calls can't reach my phone. The voice iec syslog shows

%VOICE_IEC-3-GW: C SCRIPTS: Internal Error (No dialpeer match): IEC=1.1.128.11.5.0 on callID 2164 GUID=72B7DA78C19611DF8838BFB4F5810008

So my guess is that there is a translation problem but my translation rules should be ok

malnaima · ‎09-17-2010

Hello,

It seems that your not facing the "403 Forbidden" message anymore

Now it's a dial-peer issue as per "No dialpeer match" that you posted.

As i can see from your config there is no dial-peer to match the incomming "975172273" number...

I guess your SIP provider is striping the leading zero which is causing the confusion as i can see from your translation - rule 1 /.*/ /0975172273/ -

I think you might want to change your incomming dia-peer and translation rules to match "975172273" whithout the leading zero.

Kindly Rate if info was helpfull

Best Regards,

Mahmoud

infologic · ‎09-17-2010

Yes the 0 is stripped in the messages I receive my translation rules are as follows :

voice translation-rule 1
rule 1 /.*/ /975172273/

voice translation-rule 2
rule 1 /^.*/ /404/

voice translation-profile inclid
translate called 2

voice translation-profile outclid
translate calling 1

dial-peer voice 1 voip
translation-profile incoming inclid
translation-profile outgoing outclid
destination-pattern ..........
session protocol sipv2
session target dns:sip5.voip-centrex.net
codec g711ulaw

Cisco2801#test voice translation-rule 1 404
Matched with rule 1
Original number: 404    Translated number: 975172273
Original number type: none      Translated number type: none
Original number plan: none      Translated number plan: none

Cisco2801#test voice translation-rule 2 1234567890
Matched with rule 1
Original number: 1234567890     Translated number: 404
Original number type: none      Translated number type: none
Original number plan: none      Translated number plan: none

So basicaly, all outgoing calls are translated to 975172273. This rule is sucessful given that this number is shown on the cellphone when called and appears as "unknown" is I remove the translation rule.

The result of the second test shows that any incoming call should be translated to 404 right ?

Should I put

destination-pattern 975172273

on my dial-peer voice 1 voip ?

Anyway thanks for your answers

malnaima · ‎09-17-2010

Hello,

Yes, you are correct; any incomming number according to this translation should be translated to "404" and i guess this matches an internal DN of yours.

Can you kindly update us if everything works fine now.

Best Regards,

Mahmoud

infologic · ‎09-19-2010

Situation is still the same, I get the %VOICE_IEC-3-GW: C SCRIPTS: Internal Error (No dialpeer match): IEC=1.1.128.11.5.0 on callID 2164 GUID=72B7DA78C19611DF8838BFB4F5810008 message everytime I was supposed to receive a call. Since the call is detected I don't think it could be a provider problem but more likely a configuration problem. I'm still looking into it, any help is welcome.

Ok, thanks a lot, the "incoming called-number ."

command fixed it, everything now works fine.
