Multiple IP addresses in $addr Line

1. Brekeke Product Name and Version:
3.13.0.0/552
2. Java version:

3. OS type and the version:
Windows Server 2016
4. UA (phone), gateway or other hardware/software involved:
3CX
5. Your problem:

In the Matching Rules of Dial Plans, I'm using $addr to verify that a user who's attempting to make an outbound calls is the correct user (calling from the correct public IP address).

Now I need to set up a Matching Rule that will allow for calls coming from 2 different IP addresses for one user.

For example, this particular user may be making calls from xxx.xxx.101.xxx or may be making calls from xxx.xxx.102.xxx.

I could use two dial plan entries, but doing it in one seems to make more sense.

I tried this: ^xxx.xxx.[101-102].xxx$, but through up a syntax error.
I tried this: ^xxx\.xxx\.[101-102\.xxx$, but this also through up a syntax error. This second line is very close to how the Brekeke SIP Server documentation shows doing something like this, but it must not be correct.

Can someone help me?

I think I found what I needed.

It looks like this will work:

$addr = ^xxx.xxx.101.xxx$|^xxx.xxx.102.xxx$

Is this correct?

It works.

Also it might be written as
$addr = ^xxx.xxx.10[12].xxx$

If you allow the range between xxx.xxx.101.xxx and xxx.xxx.102.xxx, you can write
$addrRange( "xxx.xxx.101.xxx", "xxx.xxx.102.xxx" ) = ^true

I also see this shown in the documentation:

$addr = ^xxx\.xxx\.101\.xxx$|^xxx\.xxx\.102\.xxx$

In this case, is it necessary to use the "\"? I've tried both with and without and it seems to work either way.

\ is an Escape character in Regular expression.
In your case, you don't have to use the "\" .

Refer to the Regular expression reference for more details.
