[OpenSIPS-Users] Remove contacts frol location table with same SIP_instance ID

[Liviu Chircu]

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,
