We recently up upgraded from CCM4.1.3 to CCM 184.108.40.20600. The upgrade went well for the most part but we have (are) facing a few issues.
MGCP ISDN PRI gateways in two offices fail when redirected to voicemail (unity). One office it was any redirected call to voicemail. This was resolved with a compination of things. The immediate workaround was to disable IE delivery completely. Telco fixed the other side by moving our span to a different isdn controller. We were able to activate the IE delivery again but had to leave the redirected IE off.
The other office is still affected by a very similar symptoms but only to one number that is a translation patter. All other numbers role to vm fine.
The other issue is with speaker phone voice quality. If the volume is to high it sounds very tinny.
My question. Are others seeing these types of issues? TAC has not been much help on the T1 side.
