PBX in SRST

Mohsin Khan Feroz · ‎08-23-2011

Dear Support,

I have a weird issue while on SRST. I have a PBX integrated with Q-Sig. The calls from the PBX works fine when the CUCM is available but in SRST the called number on the GW appears only first 5 digits where as the PBX sends 7 digits to the GW.

The scenario:

CUCM ---- GW (Q-Sig Trunk) --- PBX..

Here, the weird part is.. after the 5 digits, the GW receives the balance 2 digits one-by-one.

Something is going on with your voice translations with a combination of the dial peers. Id run a debug on the dial peers and see exactly which one its using. When you are in MGCP mode, the call is going to ignore any of this stuff until it goes through CUCM (which you must have some kind of digit manupulation going on at that point). After CUCM, it hands the call back to the router and should hit your dial peer to the PBX trunk.

acampbell · ‎08-23-2011

Hi,

I think the issue is being caused by this part of the config

!

interface Serial0/2/0:15

isdn supp-service name calling profile Network-Extension operation-value-tag local

!

This will be ignored under MGCP working.

I can not see what it point to.

Try removing it temporarilyand retest

Alex,

The command "

isdn supp-service name calling profile Network-Extension operation-value-tag local" is responsible for th calling name presentation with respect to the Q-sig interoperability with the PBX. I dont think it could cause the called number presentation on the GW from the PBX.

My Q is. why the called number is being received on the GW in the below manner

First 5 digits (30123) ENBLOC

next 2 digits (01) one-by-one.

Similarly, in the SRST itself.. The calls from the PBX DECT phone appears to be a normal 7 digits on the GW but the PBX Desk phone has the 5 digits issue.
