We have an inbound SIP solution with geographically located Contact Centers connected by MPLS with enough bandwidth. When there are packet drops in MPLS network between DC and Call Center, voice issue occurs. With 2-3 consequtive "Request Timed Out" voice starts breaking/cranking, but with more than 3-4 consequtive "Request Timed Out" the call disconnects. I can understand that RTP flow breaks with multiple RTOs and calls will disconnect. But I want to know if there is any kvp/setting in SIP/SipEndPoint (we use custom SipEndPoint with GAD) where we can control this network packet drop paramter and keep the RTP session alive for few more seconds until far end starts responding.
More information can be furnished upon request.
