I have an Audiocodes MP-118 gateway that I need to configure as a bridge from Lync to a Bogen intercom system. I followed this guide http://www.lynclog.com/2011/04/analog-phone-support-with-lync-2010.html and that worked great for the intercom phones to call out. They can call Lync extensions or call out to the outside world.

Where I'm stuck is that I can't call into the intercom system from my Lync phone.

So the intercom system is it's own closed phone system. The MP-118 is providing the dialtone for outbound calls (as if the MP-118 were a telecom provider) and the intercom is providing dialtone to the MP-118 for inbound calls.

I need to be able to call the assigned number and have the MP-118 pick up the Lync call and pass me the dial tone from the Bogen intercom system. I can then dial room numbers.

I created an Analog Device as described in the above guide. I can find that analog device in the Lync directory but when I call it I get ringing then disconnected. I suspect the problem is that Lync doesn't know where to send the calls. Like if it were a normal user it would be logged in, the MP-118 isn't "logged in" to Lync.

I hope I'm explaining myself correctly. I'm very new to phone systems.

Hi,

From your description above, it can be the issue of the dial plan. On Lync Server side, please double check the dial plan, make sure you set the correct translation rule for the numbers in Bogen intercom system. Make sure it collocates with the suitable Route and PSTN Usage.

On MP-118 side, please double check the configuration as well.
