[Asterisk-Users] MGCP

[Tim Jackson]

The ILEC here is using VocalData for doing VoIP Centrex systems etc. My
sales engineer preached SIP to me when he was talking about it, but I
actually got a hold of an engineer today, and he told me they are using
MGCP only for now. He seemed really interested in *, they are bringing
out some demo units soon for us to beta-test for them and I told him I
would show our * box to him. Maybe they might be interested in using
MGCP with it, and would be willing to help out. I'll let you know.

You could, of course, connect an MGCP ATA to FXO port(s) or device(s).
That solution degrades quality, increases delay, may have echo problems,
etc.  However, it's an easy way to get started, e.g. if you have a
spare ATA-186 that you can load some MGCP firmware into.

I am seeking a proper solution to the same problem, as my ISP in
France, Free Telecom, bundles MGCP service at very aggressive rates
(including free calls to fixed phones anywhere in France) with their
ADSL service.  I have looked at some SIP <-> MGCP and H.323 <-> MGCP
gateways, but they only talk the Call Agent side of the protocol.

If you have found a solution, please let me know.  If not, perhaps
we could work together to write one.  One possibility is enhancing
MGCP support in * to allow it to act as a User Agent.  Another is a
stand-alone script, e.g. in perl, that would do SIP <-> MGCP.
I'd be open to other suggestions, too.

Thanks,

Stewart
