4.14 Number Manipulation
This menu manages the number manipulation. In some scenarios, users need to change the
caller or callee number and then proceed with the call flow. The number manipulation on the
device can support manipulation in six directions, including PSTN->IP Callee/Caller,
PSTN->PSTN Callee/Caller, and IP->PSTN Callee/Caller. According to the call routing
direction, the manipulation rules can support number changing such as removing prefix and
adding suffix. Advanced users should pay attention to the connection routing rules and
manipulation specific requirements when using number manipulation, which can cause call
failure or other errors if not set properly.
4.14.1 PSTN -> IP Callee
On the PSTN -> IP Callee interface, you can set rules to change the actual callee number
during PSTN -> IP calling process.
Click Add, and the following interface will be displayed.
