VoIP phone cannot initiate outgoing call with R7000 Router Installed
I have had my Nighthawk R7000 Router installed and set up, it works fine except my SIP-based VoIP phone cannot make any outgoing calls anymore (it can still receive calls properly). The error code I got is SIP 400 “Bad Request”, which means the request could not be understood due to malformed syntax (RFC3261). In other words, the outgoing request has been modified by the R7000 router, so the VoIP ISP server could not understand the request anymore, the call initiation request is declined. The VoIP ADA I use is Obihai OBI202, which works perfectly with my VoIP ISP server before Nighthawk R7000 Router installation (now the OBI202 ADA has to go through R7000 router to connect to the internet). Could someone tell me how to configure the router to make sure the outgoing SIP request will not be modified? Here is the additional information: Nighthawk R7000 Firmware Version V1.0.7.12_1.2.5 OS - Windows R7 Enterprise OBI202 goes through R7000 router to connect to internet.Solved13KViews0likes11Comments
