I have several SIP trunks and one POTS line. Is it possible to continue to use the Telco VM on the POTS line? In FreePBX, I have the ring time set to 60; the provider is at 5 rings (so more than enough). When I call the trunk, it never goes to the providers voicemail, as the provider shows the call as being “answered”. It seems Asterisk grabs the line from the ATA when it rings. When I was using 3CX, that didn’t seize the line until it was answered. The ATA isn’t configured differently.
I know there are a lot of features in Asterisk VM, and many will day I should just use that, but that is not what I am looking for…yet.
To summarize: I’m looking for a caller on our POTS line to be able to leave a message in the Telco voicemail assigned to that line when not answered.
