Audio Problems
 

Martin,

I've had rercently two major problems, that make phoning quite irritating.

1) all of a sudden either me (mainly) or the counter part couldn't hear anything anymore. I had to hang up and to recall and to appologize: " .. my vioce provider .." - will that be corrected? This was not my provider's 30 or 60 min limit, it was about 10 or 15 min after the begin of the call. But I couldn't remember when it happend last time and it happens only once and a while.

2) At the start of a call (even to your echo at *600!) after my WLAN handy registered, the first two seconds were perfect and then for several moments the connection is dead. The counterpart couldn't hear anything and hang up most of the time, and I don't hear anything too! This works 'perfectly' even with your echo-service and I can easily reproduce it.

To give you an idea here is what I hear from your echo-service:
"Your about to enter an echo test. ---- latency between you and the ..

The first sentence comes immediately, clear and with no problem. After that I don't hear anything until the voice arrives 'latency' - which is quite some time - and hereafter I don't have anymore problems?

My WLAN voip-device is behind a router. There the voip-device and voip-packages have the highest priority. So why is the beginning of a connection fantastic after the device registers and then it is interrrupted for some time?

I just (12:12 Vienna Time) tried it (sad to say) successfully again and counted the seconds:
The first two seconds are very good, then I have 10-12 seconds nothing and then everything would be fine, but if I call the counterpart has allready hung up.

Hi Gooly,

The symptoms you describe sound a lot like a SIP re-invite issue. A couple of questions:

1. On the member details page, what do you have your "Symmetric NAT Handling" setting set to?

2. For the various voice service providers that you have. What do you have the "Optimize Audio Path" setting set to?

Martin,

1) "Symmetric NAT Handling" is set to Yes
2) I have only two providers, for both I have set Optimize Audio Path to No

This is acc. to your recommendations.

Greetings,
Gooly

What is the VoIP device you are using and does it have any settings that relate to SIP re-invites?

The only may-be-related settings were:
RTP Audio prt: 16050
RTP pkt Period: 10 (I am sitting right beside the router: 2m, but now set to 40 like the router)
Codec: G.711A
