Real Presence Desktop will not take incoming

[Anonymous]

We have a mac OS 10.7.5 with Real Presence Desktop on it, and it will not recieve calls. I have put itin front of our firewall with a fully routable IP address, it still wont work. I can make outgoing calls without problems. I did a port scan on the computer in question and everything looked fine. The firewall on the mac is disabled. What else can I do?

NMAP port scan:

I should say that we are on a trial with this product, and if we can't get it working we will not be buying, so far polycom has been no help.

Are you doing calls over SIP or H.323. Also are you registered to anything like a gatekeeper?

[Anonymous]

H.323 no gatekeeper, I should also note, that when we had a V700 hooked up, it worked without problems.

[Anonymous]

Can you try doing a call using SIP instead of H.323? You shouldn't have to register RPD or the farend system to anything for them to so SIP calls.

The people on the other end of the call are on an HDX system, and I have no idea how to walk them through calling over that. shouldn't the sftware answer no matter what protocol is used?

[Anonymous]

Ok well in the HDX admin settings under system go to Network/Call preference make sure they have SIP enabled. H.323 should work but it make many connections at one time. Unless you are using a Video Boarder Proxy it is hard for a firewall to route all of the handshakes that need to happen. SIP is a lot easier for a firewall to translate.

There is no firewall between this machine and the internet., It is live right now. Would you be able to test dial into our system?

[Anonymous]

Sure give me the IP address and I will test it out.

We have the same problem.  My associate can call me on my Mac and I can see her and hear her.  She cannot see or hear me.  We've opened all our ports through DMZ but there is still a problem.  Can you help?
