Hello, First of all sorry for my previous e-mauil because it was incomplete Here you have the complete one I am using freeswitch as class IV switch. I have observed that updates from SIP servers are nos passed upstream in the following scenario. IVR---(profile1)---FS---(profile2)----SBC----------GW1-----PSTN | |----------GW2-----PSTN 1. A call arrive from GW1 to the IVR 2. The IVR calls to a second phone number reachable by means of GW2 3. Once the IVR has the two calls are established the IVR do SIP bridging in order the RTP doesn't pass throuhgt it and then send two updates to FS (one for each call) to switch the calls together. 4.FS undertands the updates retaining the RTP and switching both calls, I mean, the user who made the first call is now in comunication with the user behind GW2. The question is: Why FS retain the RTP instead of send the UPDATES towards the SBC in order this one be which retain the RTP? Maybe is because the IVR and the SBC are not in the same profile? Thanks if someone has faced with this matter and have any explanation Regards 2017-03-15 13:15 GMT+01:00 Jose Serrano <jjserranor@gmail.com>:
