When assisting in setting up a direct sip trunk with Global Crossing or a direct sip trunk provider one of the issues Global Crossing comes back with is “how come the mediation server tries with so many codec’s?” a choice is not available in the current mediation server so it actually goes down the list of Codec’s in Alpha Numeric order. This is a normal condition and it will actually use the G711 U’Law which is one of the last.
