external callers cannot hear greetings

[adamgibs7]

Dears,

i have setup a unity connection for all the users, PSTN  callers cannot hear user default greetings of the user voice mail , i have enabled RTP from unity connection server to voice gateway which are in different subnet but  CUCM and UN are in 1 subnet.

Any hints where things are going wrong

Thanks

Have you verified codec support/transcoding between Unity Connection and the voice gateway?

Thanks

Anyone else can put some shade on the query above. The calls gets transferred to the unity connection I can see the call duration keeps on increasing on the mobile phone, but I cannot hear the unity connection user greeting nor whatever I speak it drops as an voice mail to the user mailbox.

thanks
