Hello,<br>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.<br>
<br>Both are asterisk 1.6<br><br>Is there any other solution from multiple SIP trunks between two asterisk boxes?<br><br>Leandro<br>
