Parameter Description
[SourceAddress] routing decisions.
The IP address can be configured in dotted-decimal notation (e.g.,
10.8.8.5) or as an FQDN. If the address is an FQDN, DNS resolution is
done according to the DNSQueryType parameter.
Notes:

The source IP address is obtained from the Contact header in the
INVITE message.

You can configure from where the source IP address is obtained,
using the SourceIPAddressInput parameter.

The source IP address can include the following wildcards:

"x": denotes single digits. For example, 10.8.8.xx represents all
the addresses between 10.8.8.10 and 10.8.8.99.

"*": denotes any number between 0 and 255. For example,
10.8.8.* represents all addresses between 10.8.8.0 and
10.8.8.255.
Operation (Destination)
Web: Hunt Group ID
[TrunkGroupId]
Defines the Hunt Group to where the incoming SIP call is sent.
Web: IP Profile ID
[ProfileId]
Assigns an IP Profile (configured in 'Configuring IP Profiles' on page 194 )
to the call.
Web: Source IP Group ID
[SrcIPGroupID]
Defines the IP Group associated with the incoming IP call. This is the IP
Group that sent the INVITE message. This IP Group can later be used as
the 'Serving IP Group' in the Account table for obtaining authentication
user name/password for this call (see 'Configuring Account Table' on
page
183 ).
22.4 IP Destinations Connectivity Feature
The device can be configured to check the integrity of the connectivity to IP destinations of
Tel-to-IP routing rules in the Outbound IP Routing table. The IP Connectivity feature can be
used for the Alternative Routing feature, whereby the device attempts to re-route calls from
unavailable Tel-to-IP routing destinations to available ones (see 'Alternative Routing Based
on IP Connectivity' on page
234 ).
The device supports the following methods for checking the connectivity of IP destinations:

Network Connectivity: The device checks the network connectivity of the IP
destination using one of the following methods configured by the 'Alt Routing Tel to IP
Connectivity Method' parameter:
•
Ping: The device periodically (every seven seconds) pings the IP destination.
•
SIP OPTIONS: The device sends "keep-alive" SIP OPTIONS messages to the IP
destination. If the device receives a SIP 200 OK in response, it considers the
destination as available. If the destination does not respond to the OPTIONS
message, then it is considered unavailable. You can configure the time interval
for sending these OPTIONS messages, using the 'Alt Routing Tel to IP Keep
Alive Time' parameter.
