• REDIRECT_TYPE [MCS | RFC3261] — is a command used to select different protocols

for IP Deskphone redirection. The default setting is MCS.

- MCS - when the IP Deskphone receives either 301 (moved permanently) or 302

(moved temporarily) during registration, it is assumed the IP Deskphone is moved

to a new system (proxy+registrar) and all subsequent messages are sent to the new

address.

- RFC3261 - the IP Deskphone assumes that, if during registration, a 301 (moved

permanently) is received, the message contains a new registrar address. The

IP Deskphone tries to register to the registrar using the existing proxy.

• ENABLE_PRACK [YES | NO] — PRACK is utilized to make some SIP messages reliable

and requires that an ACK be sent with many SIP messages. ENABLE_PRACK is often

utilized to verify that early media is being received. See RFC3262 for details.

Note:

ENABLE_PRACK must be configured as NO when connected to the MCS 5100

Release 3.5 system.

Note:

ENABLE_PRACK is provisioned after user logoff.

- NO - disables PRACK and is the default value.

- YES - enables PRACK.

• ENABLE_INTERWORKING [YES | NO] — this command is used to enable the

interworking feature to pre-authorize users or groups of users to access automatic call

answer. The configuration values are YES and NO. The default value is NO.

- NO - the interworking feature is disabled.

- YES - the interworking feature is enabled.

• ENABLE_ALLOWEDADDRESS — limits the size of the list of user and domain

addresses stored for auto-answered authorization. The default value is 100.

• PROXY_CHECKING [YES | NO] — enables and disables extra security checking when

incoming requests are sent to the IP Deskphone. The IP Deskphone with SIP Software

always sends requests through an outgoing proxy. However, it is possible, through this

configuration, to be able to accept an incoming request directly or through an incoming

proxy.

- YES - means that the request must come directly from the proxy server. YES is the

default to enable proxy checking.

- NO - means the request can be sent directly to the IP Deskphone. (NO is only

suitable in a few situations).
