> Today I have found a problem concerning asterisk 1.8.X
> I've migrated one of my servers from old version of asterisk 1.4 branch to the newest 1.8.
> Everything works fine, but faxes has stopped working.
> I've made some research and what I have found is that asterisk 1.8 has some problems with transcoding ptime, it simply does not do this, Astersik 1.4 was coping with this.
> I've attached the cap file where one of my legs is negotiating connection with ptime 10, the other one with ptime 20.
> However if you look at the payload of RTP packets it is 10 ms every where.
