Telepresence M 100 - Multipoint calls with Sony XG-80 fail

[Anonymous]

Hi,

I am having trouble with my telepresence m100. We have in our company a Sony xg80 video conference system with multi point connection possibility. When I call with Telepresence m100 to that system using H.323 protocol everything is ok. But when someone else calls for multipoint conference the system kicks me out. If I try to call there it does not allow connection. What should I do? No slightest idea how to troubleshoot 😞

Sounds like a possible firewall issue.  I cannot advise you on the Sony and cannot speculate on what it might be doing to kick you out.  The m100 uses h323 standards so there should be no problems connecting (as you said) to the Sony. Perhaps a call to your IT folks may provide some answers.

What could be wrong with the firewall? Can I see from m100 logfiles if it was firewall that kicked me out? Is there some list of ports to be opened from firewall to enable the call? And btw I tried also through VPN connection and the same happens so if I understood correctly I was inside our firewall.

Because I have no information regarding your network I can only speculate.  Firewalls configurations are frequently a source for connectivity issues.

Please review the m100 software release noted and other documents regarding the m100 configuration at the link below.

Hi,

I would need some more ideas what is wrong before going to IT:

I did some testing and I was able to make multipoint call so that from the multipoint XG-80 I did calls to similar videoconference system + polycom telepresence m100. At least this worked inside our own network. However if someone else tried to call to the multipoint device or if I tried to do the same once someone was already connected there it did not allow additional connections.

When I received the call I got notification that some firewall issue might be blocking connection but however it went through.

Could you explain what your software checks once it gives this error? Also what should we check fromour firewall which probably is somehow blocking now the incoming calls once someone else is calling in (this does not happen if we use only xg-80 devices so this must be somehow related to how telepresence m100 is using the ports?)?
