[SR-Users] Dispatcher does not go to 2nd server

[Aristeidis Tsitras]

I experience something really strange when i change the dispatcher list to
have the same priority both of the servers. I am getting 401 (unauthorised)
to the extensions trying to register. Even though they in asterisk they
seem to be registered, the debug shows 401. Not able to call from one
extension to the other.
here is the console error:

On the other hand if i change the priority to 0 & 1 the servers
respectively, then no errors in asterisk console and they can call between
each other.
This is really odd.
