[SR-Users] sip forward with manipulations

[Daniel-Constantin Mierla]

Hello,

what do you mean with:

"Both SIP trunks are IP registration only"

Does it mean that you do not know the IPs upfront (they are not static
values, they can change)? So the trunk sends REGISTER requests in order
to let the proxy know where to send traffic to it?

If you know the IP addresses upfront, then dispatcher should help (like
the others recommended).

Use ds_select_domain() to pick up round-robin sip-server2x, then use
script operations to add the number in front of domain $rd and then to
update the user part $rU

If it is the case with registrations, then let us know and we can
provide hints how to solve that one as well.

Cheers,
Daniel
