[asterisk-users] Detect IP path before calling

[Julian J. M.]

Use

qualify=3000

For an acceptable lag of up to 3 seconds. That value _doesn't_ mean to
ping the peer every 3 seconds, btw. By default, It will be pinged
every 60s if ok, and every 10s if there is any problem (peer lagged,
unreachable, etc).
