Re: [OpenSIPS-Users] Call-ID changing on re-registration
I know about the expire, I just want to ignore them because I only care when new devices register, I've tried the contact issue but it didn't help, both phones came in with the same contact.

Re: [OpenSIPS-Users] Call-ID changing on re-registration
Hello, maybe the second parameter (‘contact’) of the ‘is_contact_registered’ function [1] could be useful? And speaking about Expires: 0 — according to SIP RFC [2] it’s absolutely normal, it means tat a device disables its registration, this is done either by sending Expires: 0 SIP header, or by adding ;expires=0 as a parameter to the Contact header.

[OpenSIPS-Users] Call-ID changing on re-registration
Hi, I'm trying to run a script when a new sip device registers, I want
that if 2 devices have the same user name it should run the script
when each device registers first time, I added this script to my
REGISTER processing
if (!is_contact_registered("location",,,"$ci") && $hdr(Expires) !="0")
runscript..
I hoped this would only run once for each device registered, but I see
lots of devices changing the Call-ID for each registration, hence
running the script every few minutes instead of only once.
I also have some devices sending registrations with Expires: 0, so I
added the && $hdr(Expires) !="0" which seems to of solved that issue.
is there a better way to do this? can I have a way of knowing its the
same registration even though the Call-ID has changed?
