Something I just thought of... it could also be because you're using a board that doesn't support MTP2 signalling. Currently you have to have a Digium board (TE120/110 or TE2XXP/TE4XXP) to use mtp2 type signalling. If you're using another vendor's boards, you can still use the dchan signalling type, although it may be less reliable under load. Matthew Fredrickson
