But what I want to know is if I've specified the extensions 101 with codec, a,b,c and d and 102 with the same codec, a,b,c and d under my sip.conf. How could I know 101 is using what codec under cli when it is connected with 102?
Btw, is there any order for those codec?
i.e. if all extensions using:
disallow=all
allow=a
allow=b
allow=c
allow=d
So, the "a" will always be the first codec to use? Thanks.
