Hello Razvan,
My idea is to keep one registration per device and hence the fc1 option
wouldn't work for me here. Meaning the account can register from multiple
locations using multiple devices, but if the same device tries to initiate
a new register when there is an existing record in the location, I want to
remove the existing one and save the new one. Moreover, my clients do not
support GRUU and hence thats not the right path for me currently.
So here's the idea:
1) On a REGISTER request, my clients come with an id that is unique to a
device.
2) On successful registration, I store in local-cache the contact and
callid for this particular device-id.
3) For all REGISTER, I check if AOR with callid is registered using the
'registered("location", "AOR", "callid")' function.
4) If registered returns true for the current callid, I consider it to be a
Re-REGISTER.
5) If registered for current callid returns false, I fetch the contact for
device_id from local-cache. If the contact exists, meaning the same device
is doing a new REGISTER. In this case, I need to remove the existing
contact for this AoR.
6) This mostly happens when a client is registered and loses connectivity.
The client when restarted creates a new registration with new callid
without un-registering the existing one on the server.
7) The server deletes the device-id from the location on Un-REGISTER. I
identify this when Expires header is 0.
Do let me know if this is do-able in a neater way. Thanks in advance.
