Hi!
so after using the "sip show channels" commands i can see that most of the
the communication are under ulaw format and one or two are under gsm, do you
guys know a way to force the system to use only ulaw, is it a good idea and
is it gonna solve my static noise issue?
actually, the caller and the called hear the static noise just when handset
is used, once i use the speaker it's gone.
actual situation:
-once i use the handset to dial i can here the noise.
-i have the same model polycom phone configured with another server
(asterisk 1.4), and guess what no noise at all.
any guess!
