UC560 and lost 2 digits from Called Party Number

Hello,

i have a Problem with a UC560 and my ISDN Connection. When someone called me for example with the Number 23456-222 the called party number was 234562

I have configured my ISDN-BRI Interfaces as follow:

interface BRI0/1/0
no ip address
isdn switch-type basic-net3
isdn point-to-point-setup
isdn incoming-voice voice

isdn timer T310 200000

isdn overlap-receiving T302 20000
isdn sending-complete
isdn static-tei 0
trunk-group ALL_BRI 64

interface BRI0/1/1
  no ip address
  isdn switch-type basic-net3
  isdn point-to-point-setup
  isdn incoming-voice voice

isdn timer T310 200000

isdn overlap-receiving T302 20000
isdn sending-complete
isdn static-tei 0
trunk-group ALL_BRI 64

interface BRI0/2/0
  no ip address
  isdn switch-type basic-net3
  isdn point-to-point-setup
  isdn incoming-voice voice

isdn timer T310 200000

isdn overlap-receiving T302 20000
isdn sending-complete
isdn static-tei 0
trunk-group ALL_BRI 64

interface BRI0/2/1
  no ip address
  isdn switch-type basic-net3
  isdn point-to-point-setup
  isdn incoming-voice voice

isdn timer T310 200000

isdn overlap-receiving T302 20000
isdn sending-complete
isdn static-tei 0
trunk-group ALL_BRI 64

Any Idea?

With kind Regards

You might need to have a dial peer that waits longer to route the calls.  Might need an outbound dial-peer that ends in T so the system waits to route the call.

How does it looks ( possible entry ) that waits longer to route the calls?

Re: UC560 and lost 2 digits from Called Party Number

Hi Hartmut and Steve

I am not ever close to as good as Steve when it comes to CLI on ISR routers or UC5XX, Steve is a darn good.  Thought i would like to see the ISDN call setup coming into the UC560. To see if i can help get a little closer to what the problem may be.

But looking at the original question, the digits are getting lost coming into the UC560, so we think.

ISDN used Q.931 protocol for call control.  If we were to debug the incoming call we should maybe see some Information Element (IE)  in the setup message such as Calling party number and Called Party Number.

It would be very interesting to do a "debug isdn q931" according to the technical note  URL that follows;

http://www.cisco.com/en/US/tech/tk801/tk379/technologies_tech_note09186a0080093c1a.shtml

It would be interesting to see what exactly is the calling party number and see then if all digits are coming in for CallerId purposes.

But this is only one step of debuging.  If the digits aren't being lost , the other step is to debug the call as it gets handed off from the ISDN layer, for that I'll need some help from Steve.

Hi Dave,

here some Debug ( debug isdn q931 ). When i called the 26764228 the Called Party Number was 267642

008942: Feb  4 10:23:30.178: ISDN BR0/1/0 Q931: RX <- SETUP pd = 8  callref = 0x

        Bearer Capability i = 0x8090A3

0x81
        Progress Ind i = 0x8188 - In-band info or appropriate now available

But this is not any time. In most time the Called Party Number is correct. Tomorrow on Monday i will allways debug the ISDN-Line to see more Information.

Re: UC560 and lost 2 digits from Called Party Number

It would be important to talk to the PSTN provider and ask them to debug the calls as well. It could be that they are actually sending that called number cut off.

Re: UC560 and lost 2 digits from Called Party Number

Thats a good Idea; i will talk tommorow with the Provider to debug the incoming calls too.

Another Question for me to understand: i have read in many Forums that the incoming call was defined as " incoming called-number .T" but in my Configuration there is incoming Calls defined as "incoming called-number .%".

What is the different?

regards

Hartmut

Re: UC560 and lost 2 digits from Called Party Number

.T waits for a timeout.  .% just knows that there will be some digits, but doesn't wait on them.

This document defines your problem well.  You need an overlap receiving configuration.

Re: UC560 and lost 2 digits from Called Party Number

Ok, when i will that the UC schould wait for digits i must configure incoming called-number .T ( or only T ? )

Is this correct?

regards

    Hartmut

Re: UC560 and lost 2 digits from Called Party Number

Correct.

Re: UC560 and lost 2 digits from Called Party Number

Thank you for help; i will test it tomorrow in the office.

One Question: what is the Different between ".T" and "T"

With kind regards

Re: UC560 and lost 2 digits from Called Party Number

Hello,

i have the problem allways with lost of one or two digits.

Question for my understanding. I have in my Dial-Peer the "incoming called-number .%". Is it better to work with destination-pattern ( destination-pattern .T ) on this place?

regards

   Hartmut

Re: UC560 and lost 2 digits from Called Party Number

Follow the configuration in this guide.

http://www.cisco.com/en/US/tech/tk801/tk133/technologies_tech_note09186a00800b48cb.shtml

Use the T on the destination pattern.  You could add an extra dial-peer for this to work.

They change from destination pattern of 5 to 5T.  For you, adding a dial-peer with destination pattern of 2T should work.

Re: UC560 and lost 2 digits from Called Party Number

Question: is it correct to change the following entry in my dial-peer?

dial-peer voice 50 pots
    >> incoming called-number .%  --> destination pattern 2T
direct-inward-dial
port 0/1/0

regards

   Hartmut

Re: UC560 and lost 2 digits from Called Party Number

I would suggest making a voip dial-peer with that configuration.  Just add an extra dial-peer.

Re: UC560 and lost 2 digits from Called Party Number

Hello,

now it works.

I have in my dial-peer the entry incoming called-number .% and now it works.

>>

dial-peer voice 1 pots
trunkgroup ALL_BRI
description ISDN INCOMING ANLAGENANSCHLUSS
translation-profile incoming ISDN_INCOMING
incoming called-number .%

Thanks for all your help.
