Re: [Serusers] SER Media Proxy optik module

I can confirm this too. Just tried it in our lab with the exact same results as Klaus. (Instead of Budgetone I used ATA186). X-Lite build 1084 1. ATA186 Calls Xten. 2. Xten hears choppy audio every 5 seconds or so. 3. RTP Stream from ATA to Xten is perfect and conserves the same SSRC 4. RTP Stream from Xten to ATA switches to a new SSRC every few seconds. It is clear to me that there is a bug in Xten software. Before Xten switches to a new SSRC it attempts to send an RTP packet to the wrong RTP Port (it tries to the actual port +1). SER server sends back "ICMP Port Unreacheable (Obviously)" and Xten restarts RTP Stream on a new SSRC. I did not see any problem with Maxims RTPProxy.

RTP-analysis: RTP stream from budgetone to x-lite (via rtpproxy) is fine (no jitter, no loss) RTP stream from x-lite to budgetone (via rtpproxy): very strange: x-lite switches to a new SSRC (and seq-nr. start at 0 again) every 5 seconds. so, in my opinion: rtpproxy works fine, x-lite is guilty. but why does this happen only if the rtp proxy is involved? ...further investigations are planned...
