1. Brekeke Product Name and Version: SIP Server 3.6.3.0/454

2. Java version: 1.8.0_121-b13

3. OS type and the version: Win7 Pro

4. UA (phone), gateway or other hardware/software involved:

5. Your problem:
I would like to limit the number of simultaneous calls in a SIP trunk. Can this be done? If yes, how?

How about this?

Great, this is exactly what I was looking for, thanks. I was relying too much on the PDF...

So, to make it more complicated, if I want to restrict overall calls to 30 from a customer which may have 2 or more IP adresses as origin (like 1.1.1.1 and 2.2.2.2) AND I use a prefix for the call (like 1212), the Dial Plan rule would be:

--------------------------------------------
[Matching Patterns]
$request = ^INVITE
To = sip:1212(.+)@
$or("$addr=1\.1\.1\.1","$addr=2\.2\.2\.2") = true
$route.underlimit( "gateway1", "30" ) = true

[Deploy Patterns]
To = sip:1212%1@172.16.1.101
$routename = gateway1
$continue = true
--------------------------------------------


Right?

Try this.

Matching Patterns
$request = ^INVITE
$addr = ^1\.1\.1\.1$|^2\.2\.2\.2$
To = sip:(1212.+)@
$route.underlimit("gateway1","30") = true

Deploy Patterns
To = sip:%1@172.16.1.101
$routename = gateway1
$continue = true

This works well if the originating IP is in the From field of the INVITE.
What if this list of originating IPs is in the Contact field?
What do I play online bingo instead of $addr ?

That worked for me thanks Taitan.

$getHost(Contact) = ^1\.1\.1\.1$|^2\.2\.2\.2$

Thanks!
