I have posted about the quality of calls I have via 2talk before (http://www.geekzone.co.nz/forums.asp?ForumId=43&TopicId=37654)

I access 2talk via my desktop. Connection is Telstraclear cable (lightspeed) via wifi (N). I thought maybe it was the wifi but issue still happens when connected via ethernet cable.

It seems the issue is with landline calls, I can call mobiles fine (i.e. good quality calls) but landline calls continue to drop ( I can't hear what the other person is saying).

Any ideas on what may be causing this?

What sort of headset do you have?

Softphones are very hard to get good audio from unless you've got a very good headset and have calibrated this properly. I'd only ever recommend a good quality Bluetooth headset if you want good audio quality from a softphone.

I use a Logitech Premium Notebook Headset, it has a USB adapter but I prefer to use the plugs. Although the fact that calls to mobiles are fine and it is only calls to landlines that are affected would make me think that it is not a headset problem - feel free to correct me if I'm wrong.

Try with USB.

Also go back into the 2talk config page; untick all but G711a / G711u

Possibly it is also using different Codec for mobile calls, so this too could explain the difference.

Those codecs need more bandwidth but work well. g729, gsm and the others use less bandwidth but worse audio.

If your connection can do it, the alaw and ulaw will be the best.
