SIP Register Expiration
Duration
Enter the number of seconds your SIP account is registered with the SIP register server
before it is deleted. The Zyxel 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).
SIP Register Fall Re-try timer Enter the number of seconds the Zyxel 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 Zyxel Device lets a SIP session remain idle (without
traffic) before it automatically disconnects the session.
Min-SE Enter the minimum number of seconds the Zyxel 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 Zyxel Device accepts.
Dialing Interval Selection
Dialing Interval Selection Enter the number of seconds the Zyxel Device should wait after you stop dialing
numbers before it makes the phone call. The value depends on how quickly you dial
phone numbers.
SIP Server Location DNS
Method
Select the method that the Zyxel Device used to query the ISP’s DNS server for SIP
server address. The Zyxel Device will use the query result to locate the SIP server for
phone service registration.
Select BASIC to have the Zyxel Device query the DNS server for a DNS A record that
contains the IP address of the SIP server.
Select SRV to have the Zyxel Device query the DNS server for a DNS Service (SRV)
record. The SRV record is a list of all available SIP servers information that the DNS
server maintains. The Zyxel Device will then use the SRV record to perform A query to
get the SIP server IP. This is useful if your primary SIP server experiences difficulties,
making it hard for your IP phone users to make SIP calls.
Select NAPTR to have the Zyxel Device query the DNS server for DNS Name Authority
Pointer (NAPTR) records in order to find the available services (transport protocols)
supported by the SIP server. The Zyxel Device will then perform an SRV or A query to
get the SIP server information.
