Re: [Iaxclient-devel] Bad audio on IAX Phone <--> Cisco 7960 Call?

[Adam H. <ad...@te...>]

Strange that * would create the correct packets.

ethereal the SIP side of a pure G.711 call (IAX g.711 also), are the RTP 
frames around 20ms apart and timestamps incrementing in 320 lots (or is 
it 160)

Good luck :)
