[asterisk-users] IAX2 trunking problems

[Jon Schøpzinsky]

Hello list

We are having some strange problems.

When we setup trunking between two of our servers, the connection only uses trunking one way. Ex:

Data From callingserver to receivingserver uses trunking Data from receivingserver to callingserver does not use trunking.

I discovered this problem by looking at a tcpdump in Ethereal, and I can see that the trunked meta packets only goes one way. The other way uses normal Mini packets with raw a-law data.

Heres the configurations, with password, username and server info removed.

Callingserver:
[gsmgw1]
secret=*******
username=******
host=*******
type=peer
trunk=yes
notransfer=yes
disallow=all
allow=alaw
allow=g726

Receivingserver:
[******]
secret=*******
context=default
host=**********
type=user
accountcode=********
trunk=yes
notransfer=yes

Both servers have ztdummy module installed and loaded.

Regards
Jon Schøpzinsky
