[asterisk-users] 2-way MS-GSM support in Asterisk?

[Ray Jackson]

Hi all,

I realise Asterisk can accept an MS-GSM (65 byte) RTP stream and convert 
it to GSM etc. but can Asterisk do the reverse (i.e. send *out* a 65 
byte MS-GSM stream to a client?).  I would like to use the MS-GSM codec 
for Microsoft clients - but at the moment I am getting garbled voice 
probably due to the 33 byte GSM RTP coming back from * to the client.

Any advice on how this might be done would be welcome.

Rgds,
Ray
