I have a Lync 2010 deployment with RMX integration.
RMX 2000: 188.8.131.52
Lync 2010 (one FE server)
I've registered RMX on Lync (TCP 5060 without certificate) and used Meeting Room for dial-in from Lync clients.
Meeting rooms in the RMX had an available status.
That worked fine.
After few days, all Meeting rooms received an unknown presence, but calls to these MRs worked fine.
I've deleted and recreated Meeting Rooms and they has online status again.
Somebody faced a similar problem?
I have seen the same problem, must be a bug, although I have one meeting room with presence working and three that show as no presence.
do you use any DNS load balancers ?
The best and correct way forward is to raise a ticket with your Polycom reseller.
No, I don't use DNS load balancer. Only one FE Lyns server is on site.
If I rise a ticket, the first advice will be upgrade RMX software to the newest version. RMX has 184.108.40.206 software. I can't upgrade this RMX, because RMX is part of big system. All RMXs on this system have the same software.
I am having similar issues with my RMX-2000 on release 220.127.116.11, working with Lync 2013. The SIP integration works great but then for some unknown reason I'll come in the next morning and some random sampling of virtual rooms will be disabled.
In some cases, if I make a change to the room ID (such as change it from 5555 to 55551), save it, change it back and save again, the room automagically registers and everything is happy. If that doesn't work, then if I DELETE the room and rebuild it, it automagically starts working again.
It's as if some memory register somewhere is getting hosed and one way or the other I'm resetting the register.
And yes, I'm planning to open a support ticket with Polycom, just haven't gotten around to it yet.
I'm having the same issue, and it's not all the RMX meeting rooms at the same time. Occasionally its just one or two, other times its all of them.
This happened on my single Lync 2010 Front End and my new Lync 2013 Front End. Pretty annoying. It seems like I can call into the room via Lync and then the presence starts working again.
RMX version: 18.104.22.168
I agree about support, they will recommend I upgrade to the latest firmware which (in full respect) is quite a bit more buggy than 7.7. I've not been happy with my purchase of the RMX since I've previously owned Codian products which were rock solid :(
Edit: No DNS loan balancer in play here, I've only got a single front end server
I see some Known Issues in Polycom Release Notes.
1. BRIDGE 1322 When using an RMX with Lync, SIP registration on the meeting room is
RMX software version is unknown.
2. BRIDGE-1012 The presence status of Meeting Rooms connected to the Microsoft Lync Server might be set to "Offline" instead of "Available" when the Lync Server is reset. RMX V7.8.0
but in my case we didn't reset Lync Server and RMX has 22.214.171.124
Interesting, I hadn't tried calling into the room with Lync but that does work. This morning when I came in I found 10 out of 12 rooms were out. But just dialing into them restored the status.
It's a lot easier than deleting and rebuilding them!
Occasionally my RMX (7.7) itself will lose registration with the Lync 2010 Server. However the individual bridge rooms will stay registered, since they register to the Lync server independently of the RMX.
However, when the entire RMX loses registration to the Lync server, my Lync users cannot call into the RMX using ad-hoc bridge rooms (scheduled from the Polycom Outlook plugin). The plugin just creates a random room number, and when user's call it from Lync, it should created an ad-hoc video room on the RMX. This fails when the RMX unregisteres from the Lync front end.
The only fix is to reset the RMX.
