Register Expires. This is the expiration value, in seconds, of a REGISTER request. The System will periodically
renew registration shortly before the current registration has expired. The default is 3600.
Ans Call Without Reg. To allow inbound calls to be answered without successful registration by the System,
select yes. Otherwise, select no. The default is no.
Use DNS SRV. To use the DNS SRV lookup for proxy and outbound proxy, select yes. Otherwise, select no. The
default is no.
DNS SRV Auto Prefix. To have the System automatically prepend the proxy or outbound proxy name with
_sip._udp when it is performing a DNS SRV lookup on that name, select yes. Otherwise, select no. The default
is no.
Proxy Fallback Intvl. This sets the delay, in seconds, after which the System will retry from the highest priority
proxy (or outbound proxy) servers after it has failed over to a lower priority server. It will work only if the primary
and backup proxy server list is provided to the System via the DNS SRV record lookup on the server name. The
default is 3600.
Proxy Redundancy Method. The System will create an internal list of proxies returned in DNS SRV records. You
have a choice of two modes. Select Normal mode if you want this list to contain proxies organized by weight and
priority. Select Based on SRV Port mode if you want the System to use Normal mode first and then inspect the
port number based on the first proxy’s port on the list. The default is Normal.
Mailbox Subscribe URL. Enter the URL that should receive the SUBSCRIBE messages, so the System will receive
voicemail status notification for all mailboxes on this line.
Mailbox Deposit URL. Enter the URL that the System will contact when clients and external callers need to
deposit voicemail in any of the mailboxes on this line.
Mailbox Manage URL. Enter the URL that the IP Telephony will contact when it needs to check voicemail for any
of the mailboxes on this line.
Mailbox Status. Displayed here is the status for all mailboxes on this line. The status is automatically updated
when the System receives voicemail status notification from the ITSP. The information is shown in this format:
[mailboxID:number of new messages/number of old messages[,mailboxID:number of new messages/number of
old messages[,mailboxID:number of new messages/number of old messages[,...]]]]
