Note:
If the Internal SRV table is configured, the gateway first tries to resolve a
domain name using this table. If the domain name isn't found, the gateway
performs an SRV resolution using an external DNS server.
¾
To configure the Internal SRV table, take these 9 steps:
1.
Open the 'Internal SRV Table' screen (
Protocol Management
menu >
Routing
Tables
submenu >
Internal SRV Table
option).

5.5.4.6 Reasons for Alternative Routing
The 'Reasons for Alternative Routing' screen includes two groups: IP to Tel Reasons and
Tel to IP Reasons. Each group enables you to define up to four different release reasons. If
a call is released as a result of one of these reasons, the gateway tries to find an
alternative route to that call. The release reason for IP-to-Tel calls is provided in Q.931
notation. The release reason for Tel
Æ
IP calls is provided in SIP 4xx, 5xx, and 6xx
response codes. For Tel-to-IP calls an alternative IP address is provided; for IP-to-Tel calls
an alternative hunt (analog modules) or trunk group is provided. Refer to 'Tel to IP Routing
Table' on page
129 for information on defining an alternative IP address; refer to 'IP to Hunt
Group Routing' on page 132 for information on defining an alternative trunk group.
