asterisk users - Jul 2011 - Multiple SIP trunks between same pair of asterisk box

Hello,
for billing purpose between a multitenant asterisk box and another asterisk,
I am in the need to maintain multiple SIP trunks between them. Usually I use
insecure=invite,port but I had to remove or the trunks will be selected
based on IP address and not with username/password. I had to use the
fromuser option or asterisk will try to authenticate the call using the CID
and not the username, but this break the outbound CID of the client.

Both are asterisk 1.6

Is there any other solution from multiple SIP trunks between two asterisk
boxes?

If it is just matter of billing you can pass billing related info in
additional SIP headers on single trunk.

 

If you must need multiple trunk you can add multiple IPs of different subnet
class to both interfaces and configure asterisk to listen of all IPs. Then
use one trunk per IP Subnet class.
