[asterisk-users] Create dialplan restrictions based on the IP Address of the SIP Client?

[Raimund Sacherer]

Hello,

We have a scenario in which there are 2 sites, one in europe and one in mexico, they are connected via an IAX channel, problem is that the location in mexico has only a dynamic IP connection to the Internet.

Because of the dynamic IP I can not create IP-Tables rules to only allow this connection from the outside. But I need to restrict calls because there was a break-in which called out.

So, is it possible to restrict sip-accounts, which connect through an outside IP, to only be able to call to extensions and are not allowed to dial out?

Are there other possible solutions I am not aware of?

best regards
Ray
