SIP Phone> erase protflash
Erases the protocol area of Flash memory. Forces the phone to reset its IP stack and request its configuration files again. This command can be used only if the telnet_level parameter is set to allow privileged commands to be executed.

SIP Phone> exit
Exits the Telnet or console session.

SIP Phone> ping ip-address number packet-size timeout
Sends an Internet Control Message Protocol (ICMP) ping to a network address. You can use a dotted IP address or an alphanumeric address. The number argument specifies how many pings to send; the default value is 5. The packetsize argument defines the size of the packet; you can send any size packet up to 1480 bytes and the default packet size is 100. The timeout argument is measured in seconds and identifies how long to wait before the request times out; the default is 2.

SIP Phone> register {option value | line value}

Instructs the Cisco SIP IP phone to register with the proxy server. The keywords and argument are as follows:

option value—Specifies each line as registered or not. Valid entries are 0 (unregistered) and 1 (registered).

line value—Registers the number of lines or specifies a backup proxy. The valid values are from 1 to 6 and backup. For example, if you input register 0 backup, the phone will register to the backup proxy.

SIP Phone> reset

SIP Phone> test {open | close | key | onhook | offhook | show | hide}

–spkr—Speaker
–mute—Mute
–info—Info
–msgs—Messages

•msg—Send a message to another terminal logged into the phone; for example, you can send a message telling everyone else that is logged in to log off.

SIP Phone> traceroute ip-address [ttl]
