A bit more clarification. If I disable alaw in asterisk but everything else as described, gsm codec is being used again. So seems like the Snom 200 got a preference for alaw even if gsm is the default and has highest priority in sip.conf.
Next question is why it sounded so awfull with incoming Capi -> SIP with alaw codec to the Snom. But I can live with alaw being disabled so :) > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Lars Boegild > Thomsen > Sent: 18 May 2004 13:12 > To: [EMAIL PROTECTED] > Subject: RE: [Asterisk-Users] Problems w. chan_capi + ztdummy - SNOM > Problem? > > > Actually I've played around with the last issue quite a lot and this is > indeed getting weirder. > > Let me try to describe the problem. > > sip.conf is configured with: > > disallow = all > allow = gsm > allow = ulaw > allow = alaw > > Snom phone is configured to use GSM as default codec but with "Offer > Answer/Full" option set. > > If I place a call FROM the Snom phone to an external number (going out of > the CAPI/Fritz/ISDN interface) everything works beautifully - and > "sip show > channels" show that the Snom phone is using GSM. > > If a call come IN on the Capi interface and is routed to the > phone there is > the described pulsating sound heard on the Snom phone alone and "sip show > channels" report that ALAW is being used as codec.
