Are they any gotchas to be aware of in getting Asterisk and Lync 2013
talking to each other using SIP? Or is Lync a pretty standard implementation of SIP?
You have to use TCP for transport and you need to define the host and port address in your peer config and then secure it with ACL.

Thanks, Ish. That’s a little inconvenient. Does Lync not support standard UDP?
I have two boxes that need to talk to Lync. One is Asterisk 11, which should pose no problem with TCP, but the other is a legacy Asterisk 1.2 box, which is UDP only, I believe.

OK, I’ve found a description of Lync 2013 saying it does not support SIP over UDP, so have told the customer the 1.2 box will need a full upgrade. Thanks!
Would it not be possible to setup another more recent version of Asterisk to act as a proxy between these boxes?
