This is what makes the translation active on all proceeding inbound calls. (If I was to leave the outgoing message type as 183 but strip the SDP portion, the call will progress with no ring back and the inbound caller will experience silence throughout this time).Īpply this Message Translation to the Call Route Table from the SIP trunk. Under the Settings Tab > Telephony Mapping Tables > Message Translation. We are going to manipulate packets coming from the Mediation Server back to the SBC before it gets sent to the carrier. There isn’t a way to disable this natively in Lync/SFB Server so this is why we want to do it on the SBC. Remove the 183 Session Progress messages with SDP from the Mediation Server On the Signalling Group that connects the carrier and the SBC. Remove the 183 Session Progress messages with SDP from the Mediation Server heading back to the trunkĭisable the Early Media message from the SIP Trunk Provider passing through.Disable the Early Media message from the SIP Trunk Provider to the SBC and onward.I figured I could achieve this via stopping 2 things: Okay, we know why its happening. How can we stop this behaviour? I want to make the carrier work for their money. Simply, the sequence of these messages sent to SIP Trunk with a 183 Session Progress messages with SDP information makes the SBC decide to generate the ring back internally. The default behaviour for a Sonus SBC is to allow 183 Session Progress messages (why wouldn’t it!), which leads to Early Media during the initial call setup.

I’ll explain… What are we looking at here? As this was contributing to whom was generating the ring back in my scenario. I wanted to stop this behaviour of the Skype for Business Mediation Server sending 183 Session Progress messages to the carrier during inbound call setup. As I hunted through the SBC capture for the call setup information, I noticed the Mediation Server sends a 183 message with SDP back towards the SIP Trunk as seen in the below My aim which led to this article was to change the ringtone generation from the SBC, to be supplied by the carrier. The call setup could differ from this example. “ Ring-Ring, Ring-Ring!“.Ī notable mention is that SIP Trunk Providers are not all created equal.

This article specifically describes what to change in Skype for Business and Sonus 1000/2000 SBC to get the desired outcome with a SIP trunk. I recently had an issue with calls originating from a SIP trunk provider to Skype for Business Server(s) that needed to change who supplied the ring back tone. This would have been a much simpler process with ISDN, but SIP trunks are a much more involved PSTN connection. If you’re having problems with ring back this should help provide a quick troubleshooting step to expose a problem in this area.
