connect to ISDN with M100

My apologies, this is my first visit to the forum - tried jumping in on a previous post, but on reflection, not sure I was in the right place so have started a new thread.


I'm trialling the m100 software and have found the posts really useful, although I've not found anything that refers to using the m100 software to connect to ISDN lines.  I'm aware the majority of users are likley to be connecting between sites via IPs and not ISDN


I found the Help Notes that accompany the software leave you slightly wanting and I too have added and opened up all the appropriate ports on the firewall and my windows firewall.  I assume i still need to set up NAT with the WAN IP address so my HDX 4000 knows how to route incoming traffic?


As things stand, I currently receive "Your call could not be completed, because the call was routed through an intermediate network that does not service the far site. Contact your administrator for assistance"


I'm able to connect to most of the test sites in the contact lists and have also connected to some of the sites IPs I've seen in this thread. 


Any help appreciated

Re: connect to ISDN with M100

Hello roximaxi,


welcome to the Polycom Community.


Have you registered the m100 to any Gatekeeper or Polycom Infrastructure or just installed on the PC?


You can only make IP calls (H.323 / SIP) if the m100 is used on it's own.


Best Regards
