[OpenSIPS-Devel] [OpenSIPS-Users] [Blog] How to Eliminate Zombie Registrations in OpenSIPS

[Bogdan-Andrei Iancu]

Well, good question. The mechanism will perfectly work between the 
mid_registrar and the end-devices. But if the mid_registrar detects and 
remove a zombie contact, it may have to preform a de-registration 
(depending on the mid registrar mode) with the main registrar. That 
means an REGISTER generated by mid-registrar OpenSIPS - and if you do 
digest auth on the main registrar, this will fail :(
