[Asterisk-Users] IAX2 update - timestamp issue within iax pkts

[Ryan Thrash]

Would this fix also help random quality issues both on a LAN and also 
with a remote SIP based installation running CVS from 3/22.

We're having too frequent complaints in conjunction with Grandstream 
phones and very stuttery/choppy sound, usually outgoing to land lines, 
to the point of being unintelligible, but also on internal voicemail 
messages. Our voice LAN is a dedicated 100Mb ethernet switch for voice, 
and no general network traffic.

Thanks,
Ryan
