sip phone (ulaw) -> asterisk -> internet <- asterisk <- sip phone (ulaw)
it is possible to force the two asterisk to convert the codec from ulaw
to, say, gsm ?
i mean, without touching the two sip phones
Of course.
On the trunk between the two Asterisk servers, just add
disallow=all
allow=gsm
to the trunk config. From that point on, only GSM will transverse the trunk
and the two asterisk boxes will transcode. Remember though, transcoding
takes processor power so if you have more than one phone on each end, you
are going to eat up processor power quick.
