Hi Peter,

How exactly do you invoke the is_contact_registered() function (as params) for your script?

Hi,

Thanks for the input.

Adding the logging of $ct before call is_contact_registered show this (also added a log for when it returned false):

Aug 21 19:24:52 ip-10-100-100-62 /usr/local/sbin/opensips[21114]: CONTACT OF REGISTER: "Peter Pulham" <sip:[email protected]:49710;ob> Aug 21 19:24:52 ip-10-100-100-62 /usr/local/sbin/opensips[21114]: IS CONTACT REGISTERED RETURNED FALSE

The contact from the ul_show_contact command shows the same contact:

{
    "AOR": "[email protected] <mailto:[email protected]>",
    "Contacts": [
        {
            "Contact": "sip:[email protected]:49710;ob",
            "ContactID": "1491535901589791905",
            "Expires": 18,
            "Q": "",
            "Callid": "8..5AzWHdLmUQNXHdQhwDR3qMwOGPaWH",
            "Cseq": 56286,
            "User-agent": "Telephone 1.4",
            "Received": "sip:x.x.x.x:49710",
            "State": "CS_NEW",
            "Flags": 0,
            "Cflags": "NAT",
            "Socket": "udp:z.z.z.z:5060",
            "Methods": 8063
        }
    ]
}

y.y.y.y is the same in the log as the mi output.

Through testing, I have realised that if the contact is not NAT'd then the is_contact_registered returns true.

Any input appreciated.

    Hi Peter,

    To doublecheck, do this:

    * before calling the is_contact_registered(), use xlog() to print
    the contact you are testing (use $ct).

    * before running the test, use the ul_show_contact MI function [1]
    to print the in-memory contacts for the desired AOR.

    Hi,

    I am using mid_registrar to save registrations to the location table.

    If I use is_registered - everything works as expected. So AOR
    matching is working.

    However, when I use is_contact_registered - it returns false.

    I have checked the contact header in the request against the
    contact value of the AOR in the db and they match (the request
    has a display name but I am presuming only the uri is checked.

    The endpoint is behind NAT, but the contacts match in the db and
    request. Can some explain what is actually checked when using
    is_contact_registered?

    Many thanks
