I have read over the archives and am still a little confused about mgcp support in asterisk. I realize the mgcp channel is server side only (but jump in and correct me if I got this wrong.) I have seen a few references to sip<>mgcp interteroperability in patches, so now I am wondering what the case is with support in the code. What I actually want to do is have asterisk act as the client for an mgcp pstn gateway service (primus.ca). Can asterisk do this ? If not is there any particular technical reason in the way of a channel driver for this, or simply not the demand up till now ? The reasons for this provider choice aren't pretty - just that they are the only provider with number migration capabilities in the CO where I need them. Jon Pounder Inline Internet Systems Inc.
