Hi,
The thing that I would like to set up is essentially Asterisk as a
Media
Gateway Controller (MGC) that understands SS7. The MGC would then
control
Media Gateways such as the Cisco 5400 using MGCP (Media Gateway Control
Protocol).
I know Asterisk has some implementation of MGCP and I thought, perhaps
mistakenly, that via MGCP Asterisk could control a Media Gateway. I
was
hoping that with libss7 Asterisk would then be able to communicate to
the
SS7 network and control the Media Gateways.
It sounds like Asterisk can understand SS7 and locally - within the
box -
answer and originate calls on trunks plugged directly into the
Asterisk box.
But, from your answer, it looks like Asterisk can't then use MGCP to
control
another Media Gateway?
No. In order to do that, the channel driver that you use to terminate
your SS7 signalling link would have to be able to understand MGCP as
well. Neither libss7/chan_zap nor (AFAIK) chan_ss7 is able to talk
MGCP to media gateways directly.
Would you have any speculation about just how hard it would be to make
it
work? That is, is it a matter of some relatively simple functionality
not
You would have to add MGCP support to either chan_zap or chan_ss7.
