ISDN outgoing call failings

Plop,


I've got an issue with the ISDN calls failing.

When I used the ccs trace enable continous command, I get the following exchange

12:54:42 RO4123 DPN 28 ISRM_I ;10;*1#*50*7897006#*100*A.Gulafee*1#*19*Z#
12:54:42 RO4123 DPN 2D SSRM_I
*58*CW*@Pdt@@@@@AxVzp#*58*C6*001#*58*C4*4*1#
12:54:42 RO4123 DPN C SSRM_C 07827871873
12:54:42 RI4123 DPN 7 NIM *51*3#
12:54:42 RI4123 DPN 17 CRM/CIM ;7;*166*1 2 3 4#*234*JP#

The exchange reply busy, but my main concern is about the calling ID 7897006 which is the PNI (I've have a cluster of two ICPs) followed by the extension number of the IP set.

I tried to use the default CPN and the DID range for CPN sub but nothing to do to change that calling number.

The link is an ISDN 30 provided by virgin media.
I configured it using Euro ISDN as it's the only mode that allows me to do CPN substition (If I try Q.SIG with ETSI standard ,which I believe to be Q.93, the CPN substitution form do not include my ISDN card)

Thanks

Right,


I'm back using ISDN Euro mode. Incoming call are working fine.

Outband calls don't. The called phone rings but can't hear anything coming from the calling phone.

While the system try to connect to the called peer, the calling one can't hear any tone.


The only thing that is said in the troubleshooting guide is something to do with "audio inhibit until answer supervision after outpulsing" in the CO trunk circuit descriptor form but I don't know how to link this form with E1 links

Resolved !

Barking up the wrong tree !

Nothing to do with Mitel, the firewall was blocking the traffic on the way up...
