Hi Olle,

I pushed an additional filter for the remove() function on the development
(master) branch -- "remove by sip.instance" [1]. If demand for this feature
is popular (with all the PN setups nowadays), we may backport it to 2.4
during some future minor release.

Prior to this patch, you could not achieve this kind of filtering at all, as
"+sip.instance" is a Contact header parameter, and not a Contact URI
parameter. So when you do a lookup(), although you load up all contacts, you
lose the "+sip.instance" semantics of each one because only the Contact URIs
are relevant for the routing.

Please let me know if this works for you.

Best regards,


Liviu Chircu

We see a lot of multiple registrations from the same user with same
SIP_instance ID.


When a new registration comes in I would like to remove registrations from
the same user and SIP_Instance ID but keep all others so calls can fork in
the proper way.


So if anybody can point me in the right direction it would be much
