I have a gxv3275 here next to the 3710. I can put the same VoIP.ms account on it, register it, and make outbound calls to any number. Switch the account back to the 3710 with the same settings, nothing.
I need to do this because the access is to a shared gate controlled by people with old cell phone and landlines. They cannot use Android or IOS apps. So the doorbell needs to phone them in parallel, one of them will answer and open the gate.
It doesn’t seem to matter if the number is dialed directly by the doorbell, or if I use the other mode where a user code is entered to look up the number from the card list, or enter the number in the green “dial” box in the GUI. The call just won’t go through.
The voip.ms settings are super simple, just server, accountid/password, and it’s registered… So can’t be something wrong there. I have the outbound proxy fields blank. In the VoIP.ms GUI it not only says it’s registered, it even tells me the firmware version of the 3710.
I took a Wireshark trace and it looks fine, 3710 is sending the INVITE to the number it’s trying to call, looks like it sends it 3 times, and gets connection replies from the VoIP.ms server. What does a successful trace look like?
Any number on the whitelist can call in and it works right away.
The firewall rules are “allow” any/any. When I press the doorbell, I can see the firewall set the states in the state table. Seems like all that is working normally.
I appreciate your help, I have been working on this issue for many hours and it’s very frustrating.
