Martin,
The codec line for AstraTEL is
alaw;ulaw;g726;g729;g723
and for SIPME is
alaw;ulaw;g726;g729;g723
I'm thinking that since AstraTEL have been having lots of problems of late, maybe they have disabled g711a and g711u so that they can handle more calls with g729?
Is there anyway to see exactly what's happening between AstraTEL and my ATA? I assume from previous discussions that Voxalot does not get involved in the negotiations between my ATA and AstraTEL about which codec to use?
