We have a Patton 4112 FXO that has been configured so that each port looks like a separate gateway to the 3CX server. One line is port 5060 and the other is 5062. Our issue is on the phone side in that the Line 1 of the Fanvil phone (SIP 1) goes to port 5060 and works fine. Line 2 (SIP 2) is set for port 5062 but it won't register at all. It gets a "timeout error" and in looking at Wireshark the 3CX server does not even respond. I have noticed that each time it ties to register the Fanvil phone tries to register from a different phone port ( I don't know if this is important or not), but always to the 3CX port 5062 on Line 2. Will the 3CX only respond to a register on port 5060 and if so how do I get the phone Line 2 to be assigned to the gateway line port 5062. We need each incoming PSTN to go to a individual phone line button.
