OPENSIPS SERVER ------ CISCO ROUTER ----- SIP PHONES
Hello all,
Please forgive my ignorance on the subject but I am looking for assistance to configure a cisco ISR4331 router that sits in between Cisco SIP phones (SPA512G) and an Opensips server. The goal is to have the SIP phones directly register with the Opensips server. I have been trying for months to configure the router using the attached the information from https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/voice/cube_sipsip/configuration/xe-3s/asr1000/cube-sipsip-xe-3s-asr1000-book/voi-sip-reg-proxy.html but have not been able to get it working. Can you please let me know (1) if I am on the right track to allow for passthrough registration and (2) if there is any documentation that would assist with this task? I can upload my current configuration if needed for review.
Thanks in advance!
Nick
