Hi,

I have been looking at the usrloc module's source code to see how the uuid that is sent in +sip.instance parameter

in the Contact header. Apparently, the module ensures that only one contact per uuid exists. However the uuid

is not stored in the database.

The reason I need the uuid in the database is to access it when the iOS device is offline inorder to send a push notification.

I am using pjsip which supports sending the uuid of the device ( w/ rfc 5626 support) in the REGISTER message.

Has anyone implemented push notification using this or other methods using Kamailio?

the modules_s/usrloc keeps the sip instance in db, support k version is planned for next major release (either merge with s version and a new one combining most of the features, while keeping existing ones for safety).

However, if I got it right, it does not help storing the uuid in location table, because you want it for the case when the device is offline -- that means there is no location record for it. What you need is a separate table mapping uuid to the user, and you can build that using htable or sqlops.

You can receive the +sip.instance parameter from contact with transformations:

$(hdr(Contact){tobody.params}{param.value, +sip.instance})

Daniel
