I haven't play around enough to know whether or not the 7777 prefix is a toggle. I will do some experimenting and let you know. Right now I am prefixing all my calls with 7777.
My experience is that when the carrier's format is G723.1, you can't hear the incoming voice. When it is in G711 you can. I have made several calls using G711 and they are acceptable quality. Note that if you disallow=gsm in the sip.conf file you will get the 488 media errors you reported earlier. Below are my config files for sip and the linejack cards: ; ; SIP Configuration for Asterisk ; [general] port = 5060 ; Port to bind to bindaddr = 0.0.0.0 ; Address to bind to context=iconnect ; Default for incoming calls allow=gsm allow=ulaw allow=alaw ;register=1813342XXXX:[EMAIL PROTECTED] ;register=1202454XXXX:[EMAIL PROTECTED] [iconnecthere] type=friend username=XXXXXXXX secret=XXX host=sipauth.deltathree.com ; ; Linux Telephony Interface ; ; Configuration file ; [interfaces] mode=dialtone format=ulaw echocancel=medium silencesupression=no context=local context=default txgain=100% rxgain=100% device => /dev/phone0 On Tue, 2003-03-11 at 14:28, Jim Archer wrote: > Hi Greg and thanks very much... > > A few questions... > > First, regarding the 7777 prefix, it seemed that this acts as a toggle, > switching from the one codec to the other.
