Enabling keepalive function for a VoIP entity
After you enable keepalive function for a VoIP entity, the UA sends OPTIONS packets at the up-interval.
If the UA receives a response within the up-interval, it considers the VoIP entity to be available. If the UA
receives no response within the up-interval, or if it receives a 408, 499, or 5XX response (except for 500,
501, 502, 503, 504, and 513), it sends OPTIONS packets at the timers options interval. If the UA still
receives no responses after the maximum number of retries is reached, it considers the VoIP entity to be
unavailable.
Then, the UA sends OPTIONS packets at the down-interval. If the UA receives a response within the
down-interval, it sends OPTIONS packets at the timers options interval. If the UA still can receive
responses after the number of retries is reached, it considers the VoIP entity to be available.
