[cisco-voip] Adding a prefix to the Recieved calls list

Short story without the big nasty CCM trace snippets is that yes, the  
PSTN is sending a H225 Notify message with a ConnectedNumber IE.   
Once CCM receives this it sends the new calling party number out to  
the IP phone(s).

I have found this file with the call in, is this sufficient to find the

You can start with Q931 translator to find the call ref that matches
what is in your q931 trace.    Then search based on the calling party
number and you should see it being sent in a StationD CallInfo
message to the IP phone.

It wouldn't be in either one of those since neither call was actually
connected.  Do you have a CCM trace of the call?

Have you looked at a q931 debug on the router?  Most likely the PSTN
is sending a Connected Number IE and CM is updating the call to show
this.

I have an issue with the prefixing of digits on incoming calls, we
have 4.1(3) SR1 with H323 gateways with one ISDN30 attached, I have
added the translation rule to the config on the gateway to prefix
with 90 as shown below and this works fine for missed calls and when
the call is ringing the phone will display the number prefixed with
90 but as soon as the call is answered the display changes and drops
the 90, has anyone come across this before?



translation-rule 1

     Rule 0 ^0.% 900

     Rule 1 ^1.% 901

     Rule 2 ^2.% 902
