Each field is described in the following table.
SIP Register
Fail Re-try
timer
Enter the number of seconds the GPON Device waits before it tries again to register the SIP
account, if the first try failed or if there is no response.
Session Expires
(SE)
Enter the number of seconds the GPON Device lets a SIP session remain idle (without
traffic) before it automatically disconnects the session.
Min-SE Enter the minimum number of seconds the GPON Device lets a SIP session remain idle
(without traffic) before it automatically disconnects the session. When two SIP devices start
a SIP session, they must agree on an expiration time for idle sessions. This field is the
shortest expiration time that the GPON Device accepts.
Dialing Interval Selection
Dialing Interval
Selection
Enter the number of seconds the GPON Device should wait after you stop dialing numbers
before it makes the phone call. The value depends on how quickly you dial phone numbers.
DNS SRV
Enable DNS
SRV
Select this to have the GPON Device use DNS procedures to resolve the SIP domain and find
the SIP server’s IP address, port number and supported transport protocol(s).
The GPON Device first uses DNS Name Authority Pointer (NAPTR) records to determine the
transport protocols supported by the SIP server. It then performs DNS Service (SRV) query
to determine the port number for the protocol. The GPON Device resolves the SIP server’s
IP address by a standard DNS address record lookup.
The SIP Server Port and REGISTER Server Port fields in the General section above are
grayed out and not applicable and the Transport Type can also be set to AUTO if you
enable this option.
