Possible to automatically clear a trunk to be used for emergency calls?

[tassiliopoulos]

One thing I normally set up on a phone system with a small amount of trunks is to automatically drop a call so an emergency call can be made.

For example, on a system with 2 FXO ports, I would like to disconnect a trunk when the emergency number is dialled if 2 trunks are already off-hook.

Is this possible with the UC320?

This is called a line seizing RJ21X.  It is built into most fire/security alarm systems here in the United States.  You can purchase these line seizing apparatus separately.

Currently ido not think this is possible, and line seizure for alarm panels requires an RJ31x block. But that is not what your needing.
