5215 or 5220 IP Phone is
configured to work with a DSL
connection using PPPoE;
however, this connection cannot
be established – the phone is
stuck on “PPPoE Initialize” during
the boot program.
1. Check the PPPoE login name and
password.
2. Ensure the DSL modem is plugged in,
and powered up.
*NO REG* Appears on the 5215 or 5220 IP
Phone, indicating that the phone
has failed to register with a SIP
registration server. Connection to
a SIP registration server is
necessary for your phone to
make and receive SIP calls.
1. Ensure SIP registration server is
running.
2. If your SIP registration server is
located on the Internet, then ensure
you have a working connection to the
Internet.
3. In the SIP Configuration page of the
Web Configuration Tool, ensure that
• Bypass Firewall NAT is On
• Mode is set to Dynamic
• WAN IP Discovery URL is
correct
(http://sipdnld.mitel.com/Remote.
shtml).

• G729A & G711ALaw & G711uLaw
• G711uLaw & G711ALaw & G729A
• G711Alaw & G711uLaw & G729A.
To do this, access the Media Configuration
page of the Web Configuration Tool (see
The Web Configuration Tool on page 7).

During a conference call, neither

the same time.
Make at least one line on the phone that
initiated the conference call available.
