Prefix Rules (Emergency Call Numbers)
Click on the Add a New Prefix Number to Add
user defined PREFIX RULES.
The PREFIX RULES allows the Router to select
specific defined user agents when make outgoing
calls. There are three default prefix rules that
cannot be modified or deleted. For example, if
you add such a prefix rule:
prefix number:400 ua:sip:400683080020
Then when you call any number that is prefixed
with 400, the device will use sip:400683080020
as call out user agent.
Prefix rules is useful when add a prefix for
emergency call numbers that use PSTN as a user
agent.
Click on the Apply button to apply your settings.
