Grandstream Networks 496

HandyTone-496 User Manual Grandstream Networks, Inc.

Early Dial This parameter controls whether the phone will attempt to send an early

INVITE each time a key is pressed when a user dials a number. If set to “Yes”,

an INVITE is sent using the dial-number collected thus far; Otherwise, no

INVITE is sent until the “(Re-)Dial” button is pressed or after about 5 seconds

have elapsed if the user forgets to press the “(Re-)Dial” button.

The “Yes” option should be used ONLY if there is a SIP proxy configured and

the proxy server supports 484 Incomplete Address response. Otherwise, the call

will most likely be rejected by the proxy (with a 404 Not Found error).

Please note that this feature is NOT designed to work with and should NOT be

enabled for direct IP-to-IP calling.

Dial Plan Prefix Sets the prefix added to each dialed number

Use # as

Send Key This parameter allows users to configure the “#” key to be used as the “Send”

(or “Dial”) key. If set to “Yes”, pressing this key will immediately trigger the

sending of dialed string collected so far. In this case, this key is essentially

equivalent to the “(Re)Dial” key. If set to “No”, this “#” key will then be

included as part of the dial string to be sent out.

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

Indication will be sent periodically.

Send Anonymous

If this parameter is set to “Yes”, the “From” header in outgoing INVITE

message will be set to anonymous, essentially blocking the Caller ID from

displaying.

Lock keypad

update If this parameter is set to “Yes”, the configuration update via keypad is

disabled.

Special Feature Default is Standard. Choose the selection to meet some special requirements

from Soft Switch vendors like Lucent FS5000 Simple Endpoint, CBCOM, etc.

Distinct Ring Tones Using these settings, user can configure ring or tone frequencies according to

their preference. By default they are set to North American frequencies.

Frequencies should be configured with known values to avoid uncomfortable

high pitch sounds. ON is the period of ringing (“On time” in ‘ms’) while OFF

is the period of silence. In order to set a continuous ring, OFF should be zero.

Otherwise it will ring ON ms and a pause of OFF ms and then repeat the

pattern.

Ring 1 - 6 are reserved for distinct call waiting tones through SIP Alert-Info.

Ring 7 – 12 are distinct ring tones through SIP Alert-Info. Both client and

Server need to support this to be a useful feature. Currently, distinct ring tone

feature is only supported under Lucent Special Feature.

Volume

Amplification Handset volume adjustment. RX is for receiving volume, TX is for

transmission volume. Default values are 0dB for both parameters. +6dB

generates the highest volume and -6dB generates the lowest volume.
