Q. What is the TTL of endpoints registering with Codian internal gatekeepers?
A. Endpoints can supply a TTL (time to live) in their RRQ (registration request).
If a TTL is supplied with a value that is between 30 seconds and 5 minutes, that value is used
If the TTL supplied that is shorter than 30 seconds, then 30 seconds is used
If the TTL supplied that is longer than 5 minutes, then the value is reduced to 5 minutes
If no TTL is supplied, 5 minutes is used
