Controlling ISDN Caller ID in SRST mode

Hey Everyone

I'm sure the answer is right in front of me and I just can't see it :)

I have a H323 gateway connected to my CCM 5.1 cluster, with it's own PRI

Everything is fine normally, but if the wan link goes down and the phones go into fallback mode they cannot make calls.

From the 931 Debugs, I see the calls hitting the PRI with the correct digits, but the caller ID that is being transmitted is the 5 digit extension instead of the full DID which is causing the phone company to reject the call.

How can I get the Gateway to send correct caller ID when in SRST mode

Thanks in advance

Re: Controlling ISDN Caller ID in SRST mode

You can create a translation rule to append digits, i.e.

Assume that your internal extensions begin with 7 and are followed by 4 digits, and you are in area code 312 exchange 595

!

voice translation-rule 2

rule 1 /7\(....\)/ /312595\1/

!

voice translation-profile SRST-CALLERID

translate calling 2

call-manager-fallback

translation-profile outgoing SRST-CALLERID

How about if you apply it to an outbound dial-peer vs. callmanager-fallback?

Re: Controlling ISDN Caller ID in SRST mode

Yeah I was thinknig that....but then I' have to setup Corlists etc that would only apply in SRST mode (Need to control caller ID for other things in normal mode)

Let me give that a shot.... Was hoping to avoid that but oh well :)

Re: Controlling ISDN Caller ID in SRST mode

What about Caller name in SRST mode,can i control it?

Re: Controlling ISDN Caller ID in SRST mode

Caller name is controlled by the telco providers, they will override whatever you outpulse. For inboud calls if you see caller name (debug isdn q931) Cisco can deliver it.
