Hi all!
for a project under development, one requirement is to be able to
forward/relay the call to a specific destination depending on which IP
Address and Port the call was received by Kamailio.
This also means that Kamailio will be listening on multiple IP Address and
Ports
listen=udp:IP_1:port_1 # trunkgroup 1
listen=udp:IP_2:port_2 # trunkgroup 2
listen=udp:IP_3:port_3 # trunkgroup 3
I know the pv $Ri and $Rp can be used to identify from which IP address and
port the message reached Kamailio and having those details, depending on
the value, I can define some conditions that allows Kamailio to relay the
call to different destination endpoints.
For example:
- calls from +32 to + 39 received on trunkgroup1 needs to go to Italy SBC
address A.B.C.D
- but calls from +32 to +39 received on trunkgroup2 need to go to Germany
on SBC address 1.2.3.4 (as it is cheaper)
Is there a better way of doing this without using IF/THEN/ELSE or SWITCH
blocks and "hard code" destination SBC addresses?
I have read the DRouting module's documentation but not sure if it could
help and how...
Any suggestions?
Atenciosamente / Kind Regards / Cordialement,
