[SR-Users] Problem with auth_ephemeral and parse_uri(): bad port in uri

[Vlasis Chatzistavrou]

Hi Daniel,

Just an update, I tested this with username_format set to 1 and set the 
To: and From: headers to be the phone's username (ie without the 
timestamp). This worked without problems.

However, setting the username_format to 0 (the deprecated option) does 
not work even with the correct To: and From: headers. Since this option 
is already deprecated perhaps it could be removed in future versions to 
avoid confusion?
