Use DNS SRV:

 

Default is No. If set to Yes the client will use DNS SRV to look up

 

 

 

 

server.

 

 

 

 

 

 

 

 

 

 

 

 

User ID is Phone

 

If the BudgeTone 200 has an assigned PSTN telephone number, this

 

 

Number

 

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 whether the BudgeTone 200 needs to send

 

 

 

 

REGISTER messages to the proxy server. The default setting is “Yes”.

 

 

 

 

 

 

 

 

 

 

 

 

Unregister on

 

Default is No. If set to yes, the SIP user’s registration information will

 

 

Reboot

 

be cleared on reboot.

 

 

 

 

 

 

 

Register Expiration

 

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

 

 

 

 

that BudgeTone 200 refreshes its registration with the specified

 

 

 

 

registrar. The default interval is 60 minutes (or 1 hour). The maximum

 

 

 

 

interval is 65535 minutes (about 45 days).

 

 

 

 

 

 

 

 

 

 

 

 

Local SIP port

 

This parameter defines the local SIP port the BudgeTone 200 will 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 T1 Timeout

 

T1 is an estimate of the round-trip time (RTT) between the client and

 

 

 

 

server transactions. If the network latency is high, select bigger value

 

 

 

 

for reliable usage.

 

 

 

 

 

 

 

 

 

 

 

 

SIP T2 Interval

 

This element sets the value of the SIP protocol T2 timer, in seconds.

 

 

 

 

Timer T2 defines the retransmit interval for INVITE responses and non-

 

 

 

 

INVITE requests. The SIP protocol default value is 4 seconds.

 

 

 

 

 

 

 

 

 

 

 

 

NAT Traversal

 

This parameter defines whether the BudgeTone 200 NAT traversal

 

 

 

 

mechanism will be activated or not. If activated (by choosing “Yes”)

 

 

 

 

and a STUN server is also specified, then the BudgeTone 200 will

 

 

 

 

behave according to the STUN client specification. Under this mode,

 

 

 

 

the embedded STUN client inside the BudgeTone 200 will attempt to

 

 

 

 

detect if and what type of firewall/NAT it is sitting behind through

 

 

 

 

communication with the specified STUN server. If the detected NAT is

 

 

 

 

a Full Cone, Restricted Cone, or a Port-Restricted Cone, the BudgeTone

 

 

 

 

200 will attempt to 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 BudgeTone 200 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

 

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

 

 

MWI:

 

Indication will be sent periodically.
