Hello, Several people report that outgoing phone calls to our clients sound muffled, like they are talking underwater. Reported for both the Snom 870, and the polycom ip650. Incoming calls sound ok. Could this be a codec problem? My dialplan looks like: [general] port = 5060 bindaddr = 0.0.0.0 srvlookup = no tos_sip = cs7 tos_audio = ef registertimeout = 1 relaxdtmf = yes context = testofidea disallow = all ;allow=gsm allow = ulaw allow = alaw allow = g722 dtmfmode=rfc2833 ;; allows use of pushbuttoms ;dtmfmode = inband nat = no localnet = 10.0.0.0/255.0.0.0 canreinvite = no Thanks for any help.
