Firmware 1.1.5.15 Last Updated: 01/2008

User ID is Phone

Number

If the phone has an assigned PSTN telephone number, this field should be set to

“Yes”. Otherwise, set it to “No”. If “Yes” is set, a “user=phone” parameter will be

attached to the “From” header in SIP request

SIP Registration

This parameter controls sending REGISTER messages to the proxy server. The

default setting is “Yes”.

Un-register on Reboot

Default is No. If set to “Yes”, the SIP user’s registration information will be

cleared on reboot.

This parameter allows user to specify the time frequency (in minutes) that BT200

refreshes its registration with the specified registrar. The default interval is 60

minutes. The maximum interval is 65,535 minutes (about 45 days).

Local SIP Port

This parameter defines the local SIP port used to listen and transmit. The default

value for Account 1 is 5060. It is 5062, 5064, 5066 for Account 2, Account 3 and

Account 4 respectively.

SIP Registration Failure

Retry Wait Time

Retry registration if the process failed. Default is 20 seconds.

SIP T1 Timeout

RFC 3261 SIP T1 timer. Default is 1 second.

SIP T2 Interval

RFC 3261 SIP T2 timer. Default is 0.5 seconds.

SIP Transport Choose SIP Transport between UDP and TCP. Default is UDP.

Use RFC3581

Symmetric Routing

This option allows a SIP client to request that the server send the response back

to the source IP address and port from which the request originated.

NAT Traversal (STUN)

This parameter activates the NAT traversal mechanism. If activated (by choosing

“Yes”) and a STUN server is also specified, the phone performs according to the

STUN client specification. Using this mode, the embedded STUN client detects if

and what type of NAT/Firewall configuration is used. If the detected NAT is a Full

Cone, Restricted Cone, or a Port-Restricted Cone, the phone will use its mapped

public IP address and port in all of its SIP and SDP messages. If the NAT

Traversal field is set to “Yes” with no specified STUN server, the BT200 will

periodically (every 20 seconds or so) send a blank UDP packet (with no payload

data) to the SIP server to keep the “hole” on the NAT open.

Subscribe for MWI

Default is No. When set to “Yes” a SUBSCRIBE for Message Waiting Indication

will be sent periodically.

Proxy-Require

SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.

Voice Mail UserID

When configured, user can access messages by pressing “MSG” button. This ID

is usually the VM portal access number.

Send DTMF

This parameter specifies the mechanism to transmit DTMF digit. There are 3

supported modes: in audio which means DTMF is combined in audio signal (not

very reliable with low-bit-rate codec), via RTP (RFC2833), or via SIP INFO.

Early Dial

Default is No. Use only if proxy supports 484 response.

Dial Plan Prefix

Sets the prefix added to each dialed number.
