[Asterisk-Users] Problem playing file with G729A

[Johannes Hollerer]

Hi,

I tried to play the standard demo-echotest file !.
It works when i use an ip-phone (like x-lite or kphone), but as far as i
use an PSTN Gateway (from an VOIP Provider) to call my phone - i get the
following error:

Sep  8 14:58:33 NOTICE[-182461520]: channel.c:1691 ast_set_write_format:
Unable to find a path from GSM to G729A
Sep  8 14:58:33 WARNING[-182461520]: file.c:779 ast_streamfile: Unable
to open demo-echotest (format G729A): No such file or directory
Sep  8 14:58:33 WARNING[-182461520]: app_playback.c:83 playback_exec:
ast_streamfile failed on SIP/media-gw-45.utanet.at-097eb490 for
demo-echotest

And i hear nothing ! - What have i done wrong ?
What does it mean: Unable to find a path from GSM to G729A ??
(the file demo-echotest.gsm exists!!)
