#357 One-way sound on 3g network

I'm getting one way audio on 3g network (Vodafone CZ). Down stream has a cracking audio and sometimes when screen goes off sound stops. "Hold Wifi" option is enabled even it's useless in 3g mode.

Activating stun server (stun.ekiga.net:3478) doesn't make any difference.

The only mode that is working is UDP in Wifi.
On 3g network I can use only TCP, this is the source of all problems.

I need to mention that my configuration work in sipdroid.

Phone: HD2
System: Android 2.2 (Bangsters V1.4, CM6).

I've sent you my log files to developers(at)csipsimple(dot)com with topic "One-way sound on 3g network".

Problem solved by enabling "resolve dns sec" in network settings. Wow! It works like magic! Eventually I can make csipsimple my basic dialer! Thanks for you work.
Can't wait to test g729 codec!

Today I had another example of this issue.
I make an outgoing call in Wifi network and can't hear the person I call to. She could hear me quite well.
I switch from Wifi to 3g and everything is great like in my yesterday's post ;)

Tell me if you need logs or additional info.

Probably the STUN server was not correctly resolved temporarily .

I'll merge that with the issue that tell that there is no report about the fact there is no feedback of the fact STUN resolution failed. (issue 114)

In future release it will be possible to add several stun servers (just by separating it by ","). It will allow to improve availablity.
