Hi,
My provider uses very strange softswitch which uses payload type = 97
for dtmf transmission. I have patch to resolve this probles but it
seems incompatible with ilbc. Is it possible rewrite it with ilbc
support in mind and apply it?
I can't create new ticket because after submitting I got "Page not found" :(
