Support Posted May 11, 2017 Report Share Posted May 11, 2017 Hi, Missing audio or one way audio is generally associated with a firewall issue or the RTP unable to find ports on your system. And you arent able to hear the other party or you are not even able to hear the ringback tone when you call them? Is this happening with only you and that customer or everywhere you call (or every call which your customer receives or makes?) ? Let's narrow down the problem. Send us the screenshot of your RTP settings on Admin level and also check your firewall thoroughly. 488 error also suggests codec negotiation error.

digiline_jg Posted May 11, 2017 Author Report Share Posted May 11, 2017 only when my client call or receive a call , no sound(audio) , no tonality , nothing. before, "snomone" was installed on Windows xp , i upgraded this to Windows 10 , but the problem was the same. this problem it's very important for my customer, yesterday i updated "Snom One" to "Vodia PBX" , and since , i don't have any more problems , i'm verry happy for this , but i activated a trial version (for 30 days to test it) of Vodia PBX ten (because my licence - snom one premium ten is not compatible with "vodia pbx" software) Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted May 12, 2017 Report Share Posted May 12, 2017 What are your settings for RTP ports? Maybe you have not enough ports there. Generally speaking you should choose a range of at least a few hundred ports, or better thousand. It also helps keeping those active port numbers random, which helps reduce problems with DoS.

digiline_jg Posted May 12, 2017 Author Report Share Posted May 12, 2017 by default i use 200 ports in RTP ports config (10000 to 10200). maybe if i increases more ports , it will be better. Since i updated the soft (Snomone 5.1.3) to the new version of VodiaPBX (Version 57) , I have no more problems... i see with my customer to sell a new licence. thank you for your answers Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted May 12, 2017 Report Share Posted May 12, 2017 200 ports should be good for 50 calls: each call takes 2 x RTP and 2 x RTCP. Unless you have a very busy system this should be ok. Quote Link to comment Share on other sites More sharing options...
