I'm also getting this issue, for some reason some calls yield mass VNAK's. I also get iseq problems, but that might be my code - eg
DEBUG[98311]: File chan_iax2.c, Line 4368 (socket_read): Received iseqno 4 not within window 0->2 DEBUG[98311]: File chan_iax2.c, Line 4368 (socket_read): Received iseqno 4 not within window 0->2 DEBUG[98311]: File chan_iax2.c, Line 4368 (socket_read): Received iseqno 4 not within window 0->2 Both happen in 5% of the time. ----- Original Message ----- From: "Matt Lawson" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, December 19, 2003 7:59 AM Subject: [Asterisk-Users] Excessive VNAK's and jitter over IAX2 > Howdy, > > I recently saw something strange with a call between *'s over IAX2. > There are actually 3 *'s involved.
