Default MyNetFone/Voxalot

Just wondering if any other users are having trouble with MNF via Voxalot.
It seems since an upgrade by MNF on Saturday night I am having trouble with oneway audio - i.e. I can hear the called party answer the phone but they cannot hear me - if I bypass Voxalot using a gateway the calls are fine
I am using Sipura3000 and Billion7300A modem and this setup has been working fine with the SPA registered to Voxalot and MNF registered in Voxalot and as a gateway in the SPA - so is anyone else having problems or is it just me - thanks Bill

wildbill I am not having issues with MNF but I have the exact same issue with Pennytel. It has been driving me crazy trying all sorts of fixes.

At the moment what I did was to allow Voxalot to handle NAT, & set optimise audio to no in the sip provider settings, & at present I have 2 way audio.

Maybe give that a go?

That's the way I have it, too. I'm using MNF and Pennytel via Voxalot for both incoming and outgoing calls without any problems. I used to have trouble with incoming calls, but, since disabling port forwarding and enabling STUN, we haven't had any more problems.

Thanks I will try those settings - I had them set up as per the Voxalot tutorial for 6 steps to optimize your audio - Bill

The 6 step guide is for performance tuning rather than trouble shooting. It is actually more of a trouble maker than problem solver giving that Voxalot servers seem to have more trouble with NAT handling than other PBX'es. It is amazing that it has been there without a big warning that it could ruin your two way voice and has been recommended to solve one way voice problem for such a long time.

Well, it's not that simple,take a look at http://forum.voxalot.com/voxalot-sup...html#post11813

If the 6 step tuning works for you, it is the ideal way to go, but not all VSPs support ReInvites.....also the guide should be coupled with a STUN server in your ATA

Of course, the default VoXalot setup with enabled Symmetric NAT handling is pretty reliable, but for some cases the audio stream proxying may introduce some latency

So depends on what works in each situation, and the provider in question
