
To configure call routing between an Enterprise and two ITSPs:
1. Enable the device to register to a Proxy/Registrar server using the parameter
IsRegisterNeeded.
2. In the Proxy Sets Table page (see 'Configuring Proxy Sets Table' on page 215),
configure two Proxy Sets and for each, enable Proxy Keep-Alive (using SIP
OPTIONS) and 'round robin' load-balancing method:
•
Proxy Set #1 includes two IP addresses of the first ITSP (ITSP 1) - 10.33.37.77
and 10.33.37.79 - and using UDP.
•
Proxy Set #2 includes two IP addresses of the second ITSP (ITSP 2) - 10.8.8.40
and 10.8.8.10 - and using TCP.
The figure below displays the configuration of Proxy Set ID #1. Perform similar
configuration for Proxy Set ID #2, but using different IP addresses.
