Hi Steven,
To do that, you need to add in opensips some routing to 1) recognize the
numbers that needs to be sent to CUCM and 2)route that calls to CUCM.
For script logic it sounds like : if you receive a new call (initial
INVITE) for your local domain, check the URI and divert. If you look at
the default config file, there is comment "# requests for my domain" ->
from that point further you have only initial INVITEs for your local
domain, so you can add after:
# all numbers starting with 55 are to be sent to CUCM
if ($rU =~ "^55[0-9]+$") {
# replace the domain part of RURI to point to CUCM
rewritehostport("CUCM_IP:CUCM_PORT");
# route the call out based on RURI
route(1);
}
For the other way around, you have to put a similar logic in CUCM, like
to divert all calls starting with "12" to opensips - and replace the
domain on RURI with the IP/domain of opensips.

Hi Bogdan,
Thank you very much for your reply.
I have an Opensips Server and a Cisco Unified Communication Manager
(CUCM).
If I want to make calls from Opensips Server to CUCM and CUCM to
Opensips Server.
For example:
1) If I dial an extension number "5566" from a SIP Phone "12345" under
Opensips Server, it will try to call to a Cisco IP Phone
"5566" from CUCM through a SIP Trunk.
2) If I dial an extension number "12345" from a Cisco IP
Phone "5566" under CUCM, it will try to call to a SIP Phone "12345"
under Opensips Server through a SIP Trunk.
Can you give some instructions how to configure the above scenario for
dialing extension numbers?
Thanks

Hi Steven,
If you use the opensips default script, your opensips will accept
calls from any other external SIP entities (call targeting a local
opensips subscriber).
If you want to configure your opensips to accept foreign calls
only form a specific IP address, you can use the permission
module, with address table to implement IP-based authentication.
Best regards,
Bogdan

Hi everyone,
I am a newbie with SIP-Trunk in OpenSips.
I have a Cisco Communication Unified Manager and a OpenSips
Server running in two different Virtual Machines.
I would like to have a SIP trunk in between them "Cisco
Communication Unified Manager and OpenSips Server".
Therefore, I can make a call from OpenSips Server's SIP
Clients to Cisco IP Phone.
What should I need to add into opensips.cfg configuration file?
I hope you can give some simple examples how to do it.
I look forward to hearing from your advise asap.
Thanks
Regards,
-Steven.
