[OpenSIPS-Users] With OpenSIPS-CP how to make a sip trunk between two opensips

[Trevor Steyn]

HI Kevin.

You have already added the ips to be trusted so all that needs to be
done is the routing it depends how you want to do it but simplest from
opensips-CP is probably the drouting module you can use prefix match to
route to other sip server,

On sip server 1 you would add a gateway in the dr_gatway table with the
ip of the sip server 2

and add a rule like the following

*************************** 1. row ***************************
     ruleid: 1
    groupid: 1
     prefix: 2000
    timerec:
   priority: 0
    routeid:
     gwlist: your_sip_server_2
      attrs:
