[cisco-voip] 9971 SIP phone - no audio on calls between cluster to PSTN for certain phone numbers

[Erick B.]

Hi,

Anyone have idea here?

Have a system with 2 CUCM clusters.

Cluster 1 is CUCM version 8.6.2.22900-9 with SIP CUBE to ITSP

Cluster 2 is CUCM version 8.6.2.20000-2

ICT between the clusters (Non Gatekeeper controlled).

SCCP phones on Cluster 2 can call outbound to numbers over the ICT and out
CUBE GW fine. When a 9971 places call to same number, the call connects but
no audio is heard.
If we put the 9971 on Cluster 1 (no ICT) and same number is called it works
fine.

I've been over the release notes for 8.62a SU1 to SU3 and not finding
anything yet and have recreated the ICT and reset it. The trunk seems to be
fine since the SCCP phones work for calling the few numbers the 9971 has
trouble with. The 9971 can call most numbers just fine. 9971 is on current
firmware version to. Looking for ideas before trying to do SU3 to see if it
helps.

The number being called is a IVR with menu, etc.
