Glad you have that worked out. When an invite goes out, it offers codec choices, and typically the first agreed match is what will be used. Lesser ITSP's WILL fail a call with G722 as the first codec offered, some will look for another codec. In my experience the one that fails that negotiation is where I start running away from them as a provider. I've said it many times, not all ITSP's are equal.
