GXW4104 and Skype for Business Online Cloud Connector
« on: October 02, 2017, 05:52:16 PM »
I'm attempting to configure a GXW4104 to communicate with a mediation server in a skype for business online hybrid environment using the Cloud Connector Edition.
In my Cloud Connector config file, I specified TCP Port 5061 for the Gateway device.

I'm trying to figure out how to get the GXW4104 configured correctly...  I found lots of examples for Astreisk and FreePBX, all of which seem to have userID and Password listed in their configs.  The Cloud Connector configuration doesn't seem to provide this capability.  So how do I configure the GXW4104 to connect to the SIP trunk without specifying username and password?

here's what I've done so far:
On the Accounts Page, I set Account 1 active and set 2 and 3 NOT active.
SIP Server:  <IP Address of my Mediation Server>
SIP Settings: Registration is set to NO

Under Settings -> Channnels
Local Listen Port: ch1-4:5061++;

under VoIP:
User ID ch1-4:100;
SIP Server: ch1-4:p1;
SIP Destination port: ch1-4:5068;

FXO Lines
Stage Method: ch1-4:1;

5068 is the TCP port on the mediation server.

I'm seeing log files that look like this in my syslog:

Unfortunately, calls don't seem to route outbound - my Skype clients report "user not found" errors, and when I try inbound calls, the GXW4101 never answers the call.

Any help is appreciated!
