We are getting the specific error below on the same Unity port everytime and as a result users get blank voicemails left for them. It happens randomly. Anyone ever seen this?

We need more information in order to diagnose this. Exactly what version of Cisco Unity are you using, and what is the integration, meaning are you using Cisco Call Manager (and if so, what version) or are you using a TDM PBX (and if so, which one)? It looks like Unity is trying to recall a supervised transfer from an outside caller (3163831431 in this case) to a subscriber (either the phone was busy or they didn't answer, I can't tell which from this). For whatever reason, we're having trouble dropping the consultation call, which is a required step before we can re-establish the original call. Does this happen for all subscribers and does it happen on every call? If you place a call from an external number and then request a supervised transfer to a subscriber, is Unity able to pull the call back (1) if the phone is busy and (2) if the phone is not busy but the subscriber does not answer. And in both cases, do messages get left for the subscriber and are the messages empty?

Thanks for the response. We are using Unity 4.0(2) with 7.04TSP and Callmanager 4.01sr2. It is a unified messaging integration with Exchange 5.5 sp4 and exchange is on a separate server. It is happening for random subscribers but only on calls from the outside and only on random calls. In all cases messages get left for subscribers and sometimes they are blank audio. Also, in all cases it only on port number 2 on Unity.

I think you've run into a known defect (CSCee56053), which concerns recalling supervised transfers with Cisco Call Manager 4.0(1)sr2. That defect is fixed in 4.0(1)sr2a, which is available for download in our Technical Support Download Area. Please upgrade to that version and let us know if you're still having problems.
