Hello, I?m trying the g729 codec for testing pourpose. Whe I try to make a SIP call from a phone using g729 codec to another phone using another codec, when the destination phone answer, the call hangs up. this happend in both ways. In the asterisk console I get. Mar 4 13:11:35 NOTICE[24572]: channel.c:1724 ast_set_write_format: Unable to find a path from gsm to g729 What does it mean? Could this occur cause I am using the g729 without licence? If i buy a licence could solve my problem? Thanks. Ismael. -------------- next part -------------- An HTML attachment was scrubbed...

The error message above told you that asterisk couldn't find a valid path to convert from gsm audio to g729 audio data. Seems that should have been very obvious from the error. It is well documented had you even decided to search. -- Steven Critchfield <critch@basesys.com>
when you use Dial application without tTm options, and two User agent use same g.720 codec, The two User agent will transfer media with passthrough. You will no need to install g.729 codec module If you want some commerical G.729 codec, pls visit, http://www.voip-info.org/wiki-ITU+G.729 On Fri, 04 Mar 2005 11:13:26 -0600, Steven Critchfield <critch@basesys.com> wrote:> On Fri, 2005-03-04 at 12:02 -0500, Erick Perez wrote: > > sorry to ask, but what does it mean "in passthrough mode" ? > > data, in this case audio, passes from one side through to the other with > no need for modification.
