Interpretation
The phone's requested registration period in
seconds.
Note: The period negotiated with the server
may be different. The phone will attempt to
re-register at the beginning of the overlap
period. For example, if "expires"=300 and
"overlap"=5, the phone will re-register after
295 seconds (300-5).
The number of seconds before the expiration
time returned by server x at which the phone
should try to re-register. The phone will try to
re-register at half the expiration time returned
by the server if that value is less than the
configured overlap value.
If set to 0, calls can be routed to an outbound
proxy without registration. Refer to
reg.x.server.y.register in
<reg/>on page A-134.

If set to 0 or Null, use standard RFC 3261
signaling retry behavior. Otherwise
retryTimeOut determines how often retries
will be sent.
Units = milliSeconds. (Finest resolution =
100ms).
If set to 0 or Null, 3 is used. retryMaxCount
retries will be attempted before moving on to
the next available server.
Requested line-seize subscription period.
This attribute overrides the
voIpProt.SIP.lcs .
