Hello, What's the best way to make calls over 3G networks with less delay and more quality? any kind of compression, or different codec, any ideas? Thanks
If I recall correctly, best is use a long ptime (less overhead on network). Look in the mailing list archives for messages to/from naif (fabio pietrosanti), he has done lot of work on this. -giovanni On Mon, Sep 5, 2011 at 2:52 AM, Wagner <wagnerspi@gmail.com> wrote:

Hi, I have tested G729 and iLBC and both are working even on GPRS Edge networks. Don't forget, that many mobile operators are blocking VoIP. With one operator we had issues on some cells. In many areas his network supported VoIP in some other areas even the registration was not working. And of course don't forget, that the bandwidth is shared (and limited): in one cell you might get very good quality and in another one (or at another time) you might get very poor quality phone calls. Good luck _____ From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Wagner Sent: Monday, September 05, 2011 3:52 AM To: FreeSWITCH Users Help Subject: [Freeswitch-users] Calls over 3G Hello, What's the best way to make calls over 3G networks with less delay and more quality? any kind of compression, or different codec, any ideas?

There's always the option of using OpenVPN over a 3G network, that way it should bypass most of the restrictions placed by your mobile carrier. Not to mention that NAT-T over IPSec works well too On Mon, Sep 5, 2011 at 12:34 AM, Anestis Mavro <devel@omninet.eu> wrote:
