Well, it kinda does matter to me, if I wanted to migrate from Asterisk/OpenPBX to Call Manager or something else, because the previous PBX could no longer meet the customer's requirements. Unicall or not, having PSTN access provided via industry standard SIP/H.323 from an external box opens up lots of doors. *That* was my point. No vendor lock-in. > Where does it say that you have to have BRI/E1/T1 in order to use the > Q.931 call model? Ok, now you're not listening to what I'm saying. That was a new paragraph, a new topic in the discussion. I wasn't suggesting Q.931 could only be run over ISDN. > Now, you seem to be saying "Don't worry, we'll soon be able to only use > the SIP button and simply ignore the other buttons, at least most of the > time". No, I was questioning why businesses are effectively paying twice, for something that can these days be combined into a single, managed WAN or MPLS connection. And just to be clear, I'm not suggesting that SIP is the only thing that could run over that WAN. It's what most VoIP providers will want you to use, but if it's run by a conventional telco, they may prefer H.323. You can run IAX or MGCP over it if you really want. I don't care. Maybe I should have started a new thread or changed the email subject line to make it clearer. In a perfect world, maybe everybody would use Unicall or Q.931 signalling. But we know it's not a perfect world. At the end of day, I'm just interested in providing a solution that works, and moving on to the next paying customer. That Aston Martin won't just buy itself ya' know. To paraphrase a great American president, I'm just trying to put food on my family ;-) _______________________________________________ Openpbx-dev mailing list [email protected] http://lists.openpbx.org/mailman/listinfo/openpbx-dev
