Hello

I have sipxecs behind a pfsense router doing NAT. I had one ITSP account on it 
with a 100 number range working well. I've just added a second gateway with a 
second ITSP account to the system. They are both using the same bridge - 
'internal SBC'. They are also both using the same ITSP - Internode Nodephone 
(who run a broadworks system).

As soon as I added the second gateway and ITSP account the first one stopped 
working, and the second doesn't work either. Incoming calls are received and 
initially ring an extension however the caller gets a rejection. Subsequent 
calls are rejected. 

Looking at the logs, something appears to be looping as there's a lot of "482 
Loop detected" messages. Even after hanging up both ends there is still this 
'loop detected' message being written to the sipxbridge.log file over and over. 

When I look at the UI - Diagnostics / Internal SBC Statistics, most of the time 
the two SIP trunks have a registration status of "AUTHENTICATING", with brief 
periods of "AUTHENTICATED". 

Is this a limitation of sipx? That I can't connect to two SIP accounts at the 
same ITSP from the same server?

We have an Epygi IP PBX at a different site that is happily registering with 
two different SIP accounts both at Internode, so this can work.

Thank you
Jesse
