Reserve # in User Name

Reserve # in User Name feature allows IP phones to reserve "#" in user name. When Reserve # in
User Name feature is disabled, "#" will be converted into "%23". For example, the user registers
an account (user name: 1010#) on the phone, the phone will send 1010%23 instead of 1010# in
the REGISTER message or INVITE message to SIP server.
Example of a SIP REGISTER message:
INVITE sip:2@10.2.1.48:5060 SIP/2.0
