[cisco-voip] Unity xfer Getting 603 from carrier

[fred at browardcommunications.com]

Greetings all, this might be simple fix, I just haven’t dealt with this in a while.

We have a unity AA that, when external callers call, select menu options, etc. Unity will send the call back to. CtiRp, which then CFA to an external number. You hear the Unity transfer message, 1 second of MoH, then 10 seconds of nothing, then the call drops.

Internal calls to the CFA ctirp works

Internal calls to the unity ctirp then back to the CFA ctirp works.

I tried having unity call the pstn number directly with same results

I think the issue is with the calling number is why the carrier is sending the 603, but it is next to impossible to get them to tell us that.

Call flow:
Pstn>sipt>cucm >unity>cucm>ctirp-CFA-pstn

Where would I change the calling number being CFA’ed from Unity to the PSTN?

Any ideas?

Thank you.
