Re: [asterisk-users] IAX2 getting stuck

2017-04-20 Thread Kseniya Blashchuk 
Hmmm.. So if you are sure that the poke packets leave the network interface
(I would still check with tcpdump as well, maybe a firewall issue?) then it
makes sense to check the other side to make sure the poke packets reach
other servers.
I mean with tcpdump you may see if there are incoming packets from your
peers on the interface. If there are, then they are dropped or ignored by
your servers. If no, then it's better to check the other side.
you may try smth like 'tcpdump -npi  host  and port 4569'
Do you have a firewall configured on this server?

Sorry, I have no more ideas, then.

If routing was the problem then the SIP trunk would not work. 
Usually IAX2 is a little more forgiving about routing than SIP.


The new SIP trunks are replacing the IAX2 trunks to our other 
Asterisk servers and use exactly the same network paths, that is why I 
know it is not a network infrastructure issue.  We did turn on IAX debug 
and we only se the server trying to poke the other servers but there is 
not response or any incoming traffic.

Antony.

1- No changes to device names.  eth0 is the main link to the network, 
eth1 (also internal) goes to a SIP provider and eth2 (the USB adapter) 
goes to another SIP provider.  All IAX trunks use eth0


2- ifconfig gives the proper IP and netmask for all interfaces

3- We do not specify bindaddr or bindport in the config file as the 
default is to bind to 0.0.0.0


4- We had to make new SIP trunks to replace the IAX2 trunks to all 
servers.  The SIP trunk is working with no problems.  Except for two SIP 
links to PSTN all internal extensions use the same network interface.
