DESCRIPTION
Defines a certain SIP Response code and reason phrase for Register and Invite requests.

It allows you to smoothly move the phone between service hosts.

Never use this option unless you exactly know what you are doing!

If the phone receives that response for an Register request, it

- clears the Dirty Host Cache
- add the response transport:host:port to the dirty host cache for
   a) Retry-After: time
   b) configured dirty host ttl
   c) 5 minutes
- restart the registration process for all other hosts indicated by DNS SRV responses

5 minutes is choosed to avoid an sip registration loop.

If the phone receives that response for an Invite request, it

- add the response transport:host:port to the dirty host cache for
   a) Retry-After: time
   b) configured dirty host ttl
