Hi!
I have two pbxes connected using IAX2 and trunk=yes.
I tried the following today: From pbx1 (using a phone connected to a
TDM400P) I call pbx2 and log in via DISA.
Then I continue by calling back to pbx1. This works, and pbx2 seems to
transfer the call just fine and hangs up the channel.
If I then call pbx2 again (ie the call would be
pbx1->pbx2->pbx1->pbx2) it does not work anymore.

The effects of this are that pbx2 uses 100% cpu until the call
disconnects (which happens in about 20sec or so).

I am running CVS head as of today on both boxes.

The relevant error-messages are:
pbx1:  Lots and lots of:
 Jul  8 20:12:35 WARNING[9225]: chan_iax2.c:4893 socket_read: Received
 trunked frame before first full voice frame

pbx2:
 Jul  8 20:12:57 WARNING[9225]: chan_iax2.c:1409 attempt_transmit: Max
 retries exceeded to host x.x.x.x on IAX2[guest at pbx1]/16387
 (type = 2, subclass = 2, ts=65, seqno=2)


I tested this since I will probably be setting up a system using two
pbxes where we will be doing a lot of transfers between pbxes.
I.e. person1 on pbx1 answers and talks, transfers to person2 on
pbx2. Person2 talks some and then transfers back to person1.

Is this a known bug? An unknown bug? Or user(me) error?

/B
