Hello Everyone,
We've connected OCS to Asterisk via OpenSips, and the voice functionality is
working fine. I was wondering if anyone out there who has implemented a similar
system would be willing to share any information on how they have implemented
this, specifically with regards to URI numbering on the OCS side. So far,
we've done this:
1. Extensions in * are 4-digit, and the Caller-ID is configured with this
number. We append the area code and prefix for outbound calling. In order for
the Communicator to pop-up with the username, we've had to put the full
number with a + so that the normalized number will match the AD phone number. I
would assume that we could fiddle with the Caller-Id with macros or something to
correct this.
2. We really aren't sure how to handle the URI for OCS, since most
people will continue to use both systems. Right now, it's their 10-digit
number without the +, but I really don't know what a good solution is here.
We add a SIP channel to their Dial() statement so that the desk phone and OC
ring at the same time; we don't use Trixbox or anything like that, just a
vanilla 1.4 installation
3. Calls from OCS use the URI configured for the account, so it's
number only. I would assume there is a way to use LDAP with * to match a number
to AD information and populate it that way.
Overall, I'm fairly pleased with the setup so far. Call quality is good,
people like the ability to dial straight from Outlook and OC, and people can use
it on the road as a smartphone, without VPN access required. We have a lot of
remote users and daily conference calls, so it's going to save money for
that sort of thing as well.
Thanks,
Kevin
