Quick post here regarding my Voice over IP provider, Future Nine, and the Analog Intercom/Buzzer at the front gate of my community. When someone dials-in from the main gate, I need to pick up the phone and press 9 to open it. It has not been working as of late, and the only way to circumvent the challenge was to reset the Linksys VoIP box. It would last a few minutes.
My current internet provider is AT&T U-Verse. The VoIP box is plugged directly to the U-Verse gateway.
Future Nine replied to my concerned and suggested to make these changes under the advanced tab (LAN port, default gateway IP – http://192.168.0.1/admin/advanced)
SIP Port: 15060
I am currently testing the changes, and will update with results in the next few days.
The service is now working properly. It seems that AT&T blocks port 5060 for their own VoIP service.
