asterisk users - Mar 2006 - transcoding g723 or g729 on asterisk

Kai,

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

Hi!

No. E1s channels (which chan_ss7 uses as voice channels) can only use 
G711 alaw.

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

You have posted this three times to the ss7 list and now twice here...
we get it, you don't know how to read the information on the wiki about
installing the g729 codec. Hopefully someone here will help you by
repeating the information available there.
