[SR-Users] 420 Bad Extension error

[Daniel-Constantin Mierla]

Hello,

the REGISTER has a PATH header, the path extension has to be enabled in
registrar module -- perhaps we should make this default, given that it
is a common scenario out there to have an edge proxy/load balancer in
front of registrar.

Cheers,
Daniel
