Advanced Setup Click this to display the following advanced settings for this SIP account.
Timer Settings
Registration Period Enter the number of seconds allocated for the GPON Device to register with a SIP
service.
Register Expires Enter the number of seconds your SIP account is registered with the SIP register server
before the registration is downgraded to ‘inactive’ and all SIP functions for the account
are blocked. The GPON Device automatically tries to re-register your SIP account when
one-half of this time has passed. (The SIP register server might have a different
expiration, which takes priority over this setting.)
Register Re-send
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 Enter the number of seconds the SIP server waits for a ‘keep alive’ signal from the
GPON Device before disconnecting the call. The keep alive signal is periodically sent
from the GPON Device during a call as long as the connection between it and the server
remains constant. If interference happens somewhere along the line, or the connection
is unexpectedly terminated, then the SIP server uses this setting as a timer to
automatically disconnect the call.
Min-SE Enter the minimum number of seconds the GPON Device accepts for a session
expiration time when it receives a request to start a SIP session. If the request has a
shorter time, the GPON Device rejects it.
DSCP Tag
SIP DSCP Priority
Setting Enter the DSCP (DiffServ Code Point) number for SIP message transmissions. The
Device creates Class of Service (CoS) priority tags with this number to SIP traffic that it
transmits.
RTP DSCP Priority
Setting Enter the DSCP (DiffServ Code Point) number for RTP voice transmissions. The Device
creates Class of Service (CoS) priority tags with this number to RTP traffic that it
transmits.
RTP Port Range
Start Port
End Port
Enter the listening port number(s) for RTP traffic, if your VoIP service provider gave you
this information. Otherwise, keep the default values.

To enter a range of ports,
• enter the port number at the beginning of the range in the Start Port field
• enter the port number at the end of the range in the End Port field.
