Hi all, Thank you for the reply. I didn't want to bother the list too much. However, after reading I
discover I don’t have a clear cut way of doing transcoding. Can somebody direct me to where I can get document to get this
transcoding done. My set up From [cisco (g729)] ----> [asterisk (sip
channel(g729)within the same asterisk) g711 to chan_ss7] -----> [pstn] And vice versa. I will be glad if someone can throw more light on this for me. Goksie -----Original Message----- From: [EMAIL PROTECTED]

You can do transcoding on the asterisk machine that you use as SS7 Gateway. This means you get the calls delivered via SIP with G723 and send them out to SS7 with G711. Note that you need more processingpower for this then if you do no transcoding. Best regards Kai -- Kai Militzer
