[cisco-voip] Unity Connection > SIP/CUCM > SCCP Attendant Console

[Brian Meade]

Might need to switch to supervised transfer instead of release to switch.
Traces will help show root cause.  I've seen this issue when some devices
don't like a SIP Update before the call is connected and respond with 491
Request Pending.
