Hi,

the most trivial way is:

if (src_ip==111.222.111.222) { }

Perhaps the Source IP address pseudo variable is what you are looking for.

Reference to it can be found at: http://openser.org/docs/pseudo-variables-1.1.x.htm Section: 3.45. IP source address

With $si on one side of the equation, you need something on the other side. This can be perhaps a hardcoded IP address or perhaps an $avp() variable. Pretty much any business logic can be used to pull an IP out of a database table and put it into an avp variable.

With $si on one side of the equation and an $avp() on the other, you can then perform various comparisons.

Another approach might be to use the permissions module and the "trusted" table. Using this method, a simple "allow_trusted()" call can be made to determine is an address is "trusted".

Hope this helps.

Regards, Norm

What is the best way to detect whether an INVITE message came from a certain IP address? I.e. if a call comes from a certain asterisk box?

I have thought of using the textops search(), but this seems a little clumsy. Perhaps there is a way to get directly at the via headers? Or is there a keyword of corresponding functionality to the uri keyword?

Thanks, Mark Price
