asterisk users - May 2007 - Basic connection between Mitel 3300 ICP and Asterisk (trixbox) - from a clueless newbie....

Hi all,

Our company has deployed a Mitel 3300 system (only about 2.5 years ago)
and we are experimenting with setting up Asterisk in our head office
(for business continuity, ie we have a bird flu epidemic and no-one can
come in, therefore use SIP softphones at home to co-ordinate activity)
and at a remote site in the Isle of Man (connected via 2Mbps SDSL)

Ideally we'd like anyone on either Asterisk servers (IOM and London) to
be able to dial anyone internally on the Mitel 3300 and vice-versa. We
have got *one* SIP license so far for the Mitel for testing purposes.

I am a bit crap on telephony, but as I have gathered so far we should be
able to connect the two systems via either QSIG (with an appropriate
card on the Asterisk server), DPNSS (which I'm not sure if any Asterisk
compatible hardware supports) or SIP (I'm happy setting up clients, but
have no clue with inter-PBX stuff).

I don't really care about any special features as long as the Mitel
numbers can call SIP users in London or IOM and the other way round.

I am planning to get at least 1 BRI pulled into the IOM office for PSTN
access, btw.

Any help you can offer would be gratefully received.

Cheers

Alex

Good morning,

We are in the process of setting up a similar  combination - Mitel 3300 ICP
+ Asterisk. We chose to use SIP for interconnectivity for ease of
configuration inhouse as getting the local Mitel support rep is tough and
they balk at any configuration beyond the basics and you know we IT guys
always want more! E1 cards equally work. Google has loads of links to SIP
configuration, troubleshooting, interoperability etc

We got SIP Trunk Licenses for the Mitel 3300ICP. Mitel talks to Asterisk
which connects remote Cisco Routers (routers have fxs ports that connect
local PBX into voip network) + other remote Asterisk boxes + SIP soft
phones. High cost of licensing on Mitel was the the primary advantage for
choosing Asterisk. Also, access to Mitel documentation is limited (even
google search turns up sparse information).

If there are specific questions, please ask, would be glad to respond.

Regards, Joesph
