Redirecting Number Missing in Q931 Setup

Hi, I have the following problem. A redirected call comes from CUCM to H323 VGW and leave Pots  Dialpeer BRI S0 ISDN as a Q931 Setup Message. But redirected number is  not seeing in Outgoing Q931 Setup, only the Calling and Called Party  Number. CUCM is transmit redirected number fine to the VGW.

It should be transmitt also the Redirected Number at Pots Dialpeer Voice Port BRI S0.

Any help are appriciate.

Thanks in ahead.

Redirecting Number Missing in Q931 Setup

Hi Armin,

Is the redirection done within the call manager?

Do you have "Redirecting Number IE delivery - Outbound" checked on the H323 gateway in the call manager? Please if not already, please check it and reset the gateway (off production hours).

Re: Redirecting Number Missing in Q931 Setup

Hi, yes, it is a IP phone in CUCM they have CFA.

PSTN Call into VGW--> H323-- CUCM--> Ip Phone 106 Divert to 62225 ---> H323 ---- VGW ---- interface BRI0/1/0 --- S0 third party voice server

The Redirect Number recieve the IOS VGW. I see that in the Trace at  the Voice GW. I have found the problem now. After I set this Parameter

tkgwdemo(config-if)#isdn out ie redirecting-number

it works.

Here the config.
