FYI, I was having problems getting chan_misdn to work, it just wouldn't get the extension in immediate mode. chan_capi got the extension okay but the audio quality was awful. In the end, I put a Wait(0.01) before Answer in the incoming mISDN context, then DISA(no-password|sip_provider_out) and now I can make calls from the legacy PBX out to the SIP provider. Woohoo! This isn't the first time a small Wait has fixed something for me!!! James
