Hi all,

Perhaps someone has dealt with it before.

I want to activate a bunch of my own scripts after someone has registred
om my asterisk, or when his cient has de-registerded.

have been skimming through AGI and AMI, and seen a lot of nice features,
but not the (de-)registering events.

Kind regards, Hans

  • On Asterisk 1.8 when a SIP peer resgisters or unregisters it generates
    a PeerStatus event. I don’t know if this is in 1.4/1.6 as well, but
    should be easy enough to test.

    Here is an example of what I see on the manager interface during a
    register/unregister:

    Event: PeerStatus
    Privilege: system,all
    ChannelType: SIP
    Peer: SIP/twinkle
    PeerStatus: Registered
    Address: 192.168.56.1:5068

    Event: PeerStatus
    Privilege: system,all
    ChannelType: SIP
    Peer: SIP/twinkle
    PeerStatus: Unregistered

    I think that should work for whatever you need to do.

  • I’m doing a fresh install, so 1.8 is what i’m going to use.

    What i want to check, is whether to person who is doing a register, is
    realy the person at the other end of a VPN-tunnel.
    With openvpn i’m absolutely sure which person is at a certain
    vpn-ip-addres. I must check if the registering is faked or not.

    As ong as linphone (or for that matter any other softphone) does not
    have a possibility for using the libraries from opensc, there is no
    other way…

    So next couple of weeks i’ll start exploring AMI,

    Thanks!

  • Well, if that’s all you need (restricting registrations for a SIP
    endpoint to a specific IP address), try one of the following
    methods…

    Method 1:
    In the endpoint definition, set the host to the vpn ip address, rather
    than setting it to dynamic. This disallows registrations. Then, use
    qualify=yes so Asterisk “knows” when the endpoint is available
    (responding to OPTIONS requests).

    Method 2:
    Use the permit,deny, and mask settings to define what ip address
    and/or network the endpoint should be at, thereby locking out use from
    another address.
    (http://www.voip-info.org/wiki/view/Asterisk+sip+permit-deny-mask)

    Either of those should resolve your needs

  • No, don’t think so, (unless mistaken)
    Everybody got a dynamic address from openvpn, something in 10.225.0.0/16
    You never know what you wil get, so it got to be dynamic.

    Anybody within that range is a valid user (otherwise he could not set up
    the vpn-tunnel). But any rogue co-worker should not be able to register
    as another co-worker, so method-2 won’t do either.

    sip/tls might have been a solution, but private keys are locked on a
    card, and can ony be reached with the pkcs11-libs from opensc.
