Hi Peter,
Indeed, that's a good point - the `fix_nated_contact()` is changing the
contact (with the IP and port from the network level), messing up the
matching.

Hi,
A bit more testing and I realised that if I xlog the contact $ct it
printed the value of the contact in the INVITE:
<sip:[email protected]:49710;ob>
Which looked fine and matched the usrloc table. However, if I xlog
$ct.field(uri) it printed a value with the public IP:
sip:[email protected]:49710;ob
So it looks like I need to do my checking before I do any NAT contact
fixup.
This also explains why non NAT'd contacts were working.
Thanks for the help, set me on the right path to finally get to the issue.
Many thanks

In this case, the function will perform a string matching between
the first valid contact URI from the message and the registered
contacts (the `Contact` field). Again, it is a string matching
over the entire SIP URI.
So far, based on your logs, I would say they should match. Could
you doublecheck again ?

Hi,
I am calling is_contact_registered("location")
For the mi command, I used "mi ul_show_contact location
[email protected] <mailto:[email protected]>" in opensips-cli
Many thanks

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
