Limit call to one per route

[stakano]

I would like to limit my calls to one per route, because my ITSP has a limit of 2 channels per DID.

How can this be done?

I've never actually tried this, but try unchecking the "Multiple Logons" option in the IP-PSTN call routing rule.

Seems that's something that might work.

Actually that "Multiple Logons" option is specially designed for that, so it should work After a call is done using such rule, the rule becomes virtually disabled until the call is terminated.
