This is an interesting, and somewhat common problem.
To fully understand the call set up and TEAR DOWN, you need to devote a
number hours to
reading on the 'net. You will need to understand the various VoIP Protocols
You need to understand that a "SIP" adapter MAY NOT be the answer !

Howdy, guys.
Wondering if anyone has some thoughts on this: I have a VOIP gateway (Telco Systems AC211) which thinks the 1232 is off-hook for days at a time, when of course it's not. A 2500 set works fine on the same gateway.
All I can think is that the gateway may not be pumping out enough current for
the 1232 to accurately recognize on/off-hook status. I've been told by Telco
Systems that they believe the gateway puts out 48V at about 20 mA. Is that
enough? The VOIP provider (Sunrocket) doesn't have any ideas at this point.
Anyone know what the spec is for the 1232 on this item? I wasn't able to find
that out, myself.
Thanks very much!
