I’m posting this here as this problem seems to be specific to Sangoma phones only at the moment.
I have some new S700 phones that I received this week. I’ve just cut the FrreePBX distro (latest version fully patched) running Edge over to the supplied sound language files. I’m Australia and installed the en_AU language files from Sound Language under Admin. I initially installed G722 and alaw files. The S700 is setup to use G722 as its default codec and is configured via Endpoint Manager.
When I go to voicemail (*98), for example, to test the new sound files, I get silence from the S700. The phone shows G722 on its display. The asterisk logs clearly show the g722 file being played without error. If I use one of my other phones (Siemens Gigaset using G722 or Bria setup to use G722) then I hear the high quality sound.
If I remove the G722 sounds (leaving alaw), then the I can hear the lower quality audio prompts. All of the other devices can as well.
Any ideas on how I can troubleshoot this further? Is it a problem with the audio files, the S700 or something else?
