Hi RTPProxy users, Our company is still experiencing major upstream-quality issues (IP->PSTN) with our voice-service. We've OpenSer 1.3 in combination with RTPProxy to which all our customers connect. OpenSer forwards these calls to our ITSP, which terminates the calls to the PSTN. The PSTN-side of the call experiences jitter etc. on the call. The IP-side of the call hears the PSTN-side correct.
I've placed a monitor (whireshark) on the exit point of our network. From then on it's our ITSP (direct leased-line). Next to that i've listened to several calls from which our customers say it's a bad call. These calls sound ok! So it must be our ITSP (or the leased line) which is causing the problems. But still the ITSP claims there's nothing wrong on their side of the network. They also have a monitor on their PSTN-gateway, and they're seeing a large jitter on our calls. Since it's impossible for me to listen to all the problem-calls I have the following questions: When analyzing the wireshark calls, it also displays the jitter, lost packets and max. delta. Are these values applicable for the complete call (so from customer to OpenSer/RTPProxy to the exitpoint), or only from OpenSer/RTPProxy to the exit-point? I ask this, because it is still possible that there are some packets lost before it enters OpenSer. Would Whireshark notice this? I've asking these kind of questions for several times now. But i'm going mad in analyzing for the cause of these problems. I still think it's our ITSP, but I need some definite proof of this. Simply saying: choose another ITSP isn't that simple. There aren't that many ITSP here around. Thank you for taking the time reading this message, and perhaps answering it!!!
