Reserve # in User Name
Reserve # in User Name feature allows the phones to reserve “#” in user name. When Reserve # in User Name fea-
ture 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 the
SIP server.
Example of a SIP REGISTER message:
INVITE sip:2@10.2.1.48:5060 SIP/2.0
Via: SIP/2.0/UDP 10.3.20.6:5060;branch=z9hG4bK1867789050
