[asterisk-users] FAX

[michel freiha]

Dear Sir,

What do you mean by manual fax? I need to offer the ability for each
extension to use voice and FAX...MAybe the voice will use G729 and the FAX
ulaw for the same extension...If I configure the device in a manner that use
ulaw for FAX and G729 for voice then this should work smoothly with an
extension where G729,ulaw, alaw are allowed?

Regards
