Hello, 

I need some help with the display name in FS here is my issue.

Currently with FS if the A-LEG call invite is in the following format

From: <sip:82617268@IPADDRESS>;tag=15074010004646399782

FS then will convert this to 

From: "82617268" <sip:82617268@IPADDRESS>;tag=82DmgpptX99ym

What I need to be able to get FS to do is on invites that the display-name is blank that the output is also blank so no "" or no "NUMBER" based on the SIP RFC section 8.1.1.3 it states that the following methods are valid

      From: "Bob" <sips:bob@biloxi.com> ;tag=a48s
      From: sip:+12125551212@phone2net.com;tag=887s
      From: Anonymous <sip:c8oqz84zk7z@privacy.org>;tag=hyh8

So in the situation where there is no display-name presented to FS, FS should use option 2 in situations where FS does receive a display-name then option one is a valid choice.

Thanks for your help in this matter..
