[cisco-voip] Dialing to H.323. GW

[Dschulz]

You will want to confirm if the voice mail system is doing onboard transcoding, or they are going to need to provide a transcoder for the codec converserion.  Also, check the audio record format, which i am assuming is not G.729.  HTH.

Hi Mike -

You said that as soon as voice mail tries to pick up it goes busy.  What
voice mail are you using?  Some voice mail systems only do G.711, which
would cause this to happen (without an available transcoder).  Do you have
transcoders available at this location.

If you are using Unity the transcoding is onboard.  If you are using Unity
Connection, then the phone system is required to transcode.

HTH.
