SIP trunk on separate network.

[TimoM]

Hi, I have a client with on site 3CX with local IP (say) 192.168.10.20. The local SIP provider has given an IP of 10.22.x.x provided via a router on site with a direct ethernet cable to the local Switch. They have mapped an IP on their router to a local one (say) 192.168.10.21 which will route traffic to the 10.22.x.x. How can I add a static route for this particular SIP provider, leaving the default route intact?

Hi!

I have a provider in mind for which we do have instructions on how to set Static Routes on the OS as well as the settings you need to make in the "Options" tab to the "Select which IP to use in 'Contact' (SIP) and 'Connection'(SDP) fields".
