[OpenSIPS-Users] re-REGISTER with To tag gets 404

[Jeff Pyle]

Hello,

The default config of Opensips takes any packet with a To tag but that
doesn't fall into the loose_route() category and responds with a 404 Not
here.  My config is based largely on the default one and contains this
portion.

I'm testing the SIP capabilities of a Mitel 5000 PBX.  The initial
registration is fine, but re-registrations contain To tag presented to the
Mitel in the 200 OK of the initial registration.  These re-registrations
receive the 404 Not here response.

Looking into RFC3261 I don't see anything specific to REGISTERs, only that
(paraphrased) subsequent transactions within a dialog should contain the
tags of the initial transaction.

Is the Mitel doing something wrong according to the RFC, or is the default
config mistreating this somehow?  Should an exception be added for
REGISTERs?


Thanks,
Jeff
