Samung OS7070 + OpenVox VS-GGU-E2M0400

we are trying to solve a huge problem with GSM OpenVox within 2 weeks already and no luck (
we have Samsung OS7070 + GSM OpenVox with 8 GSM channels in cluster
when MPS service on Samsung is disabled - all calls are performing well
but when I enable MPS on Samsung station - that's it.....in 30-40% of calls we have silence in two ways

Samsung and openvox in the same local network... but Samsung uses for MGI RTP ports 30000-30015, for MPS RTP ports 40000-40017 & 45xxx
so when we enabling MPS on Samsung - 30% of calls with silence in two ways

Could you please help to find out problem? tcpdump traces checked on samsung side - all in good shape

Hi,

As you said, if disable MPS on Samsung station, everything is ok. So our gsm gateway work good.
it's the configuration of Samsung OS7070 causes the call problem. So please contact the Samsung support experts to help you.

MPS service means just to work on ports 40000-40017. thats it.

so you are wrong.

Samsung MPS service works within 10 years on RTP port 40000-40017 and there are no problems reported about that.
So we need to understand why when traffic goes from OpenVox on those port we have a problem in 30% of cases...

Could you check pls openvox ocnfiguration? maybe openvox cant send RTP traffic properly on those ports?

thank you

Hi,

Do you mean you use ports 40000-40017 to send and receive voice packages?
Could you add my skype for convenient contact?
