From: Bruce Atherton <[EMAIL PROTECTED]> That is really good news. So the problem must just be with Asterisk, which happens to be the PBX I am testing with. I will take the issue up with the developers there.
Well, I know that the open-source sipX PBX doesn't have this problem -- when you use it with several popular brands of PSTN gateway. But sipX is "pure SIP", the PBX really is a proxy, and the two endpoints are swapping status info, so if the gateway is well-behaved, your UA will see the right things. Asterisk isn't done that way, because SIP was retrofitted onto another protocol (IXA), so your UA talks SIP to Asterisk, which talks SIP to the gateway; really two SIP dialogs which together do the job. That being said, though, I would be surprised if Asterisk sends your UA a 200 before the gateway sends Asterisk a 200, to avoid exactly the problems you mention. I'd check with the Asterisk developers, and make sure you tell them which the gateway device you're using. You're running into something that has to be unusual.
