Hi,

I'm having trouble connecting two Asterisk boxes via a IAX2 friend trunk.
"iax2 show peers" on both boxes seem to show that all's fine (Status OK on qualify=yes peer).
voip1 is an Asterisk 1.2.27 production server.
voip2 is an Asterisk 1.4.21 experimental server in the same gigabit LAN.
If I register a SIP extension on voip2 and call an external number via the iax2 friend trunk then the call works fine (call flows from voip2 to voip1 to PSTN).
However, after hanging up there's no way I can place another call through this trunk.
The trunk's name is "interbox" (see below) and its peer status on voip2 (192.168.250.112) becomes UNREACHABLE while voip1 (192.168.250.111) is still OK.
The only way I found to make the trunk "work" again is to restart Asterisk 1.4.21 on voip2 (actually had to kill the process).
The bug is easily reproducible on my machines.

So it seems that voip2's IAX service is having major problems. I'm aware that there have been quite a few changes lately in 1.4 regarding IAX. Is anyone else experiencing this?

I would also like to point out an issue regarding the CLI in 1.4.21 which I believe has already been reported on this mailing list but it doesn't seem to have been addressed.
Subsequent "iax2 show channels" and "iax2 show peers" (and probably other commands) do not output anything. Only the first instance does. One has to quit the cli and open another console.

Thanks in advance.

Some info (please ignore "priv" which is a iax trunk for DUNDi lookups):

voip1 iax.conf:

[interbox]
deny=all
allow=alaw
allow=ulaw
allow=gsm
allow=ilbc
allow=g729
type=friend
host=192.168.250.112
secret=mysecret
auth=plaintext
qualify=yes
context=outbound-thru-interbox

[priv]
type=friend ; or peer
dbsecret=dundi/secret
qualify=yes
context=dundi-incoming

(similar iax.conf config for voip2)
