SIP T1 Timeout

 

T1 is an estimate of the round-trip time between the client and server transactions.

 

 

 

 

 

 

If the network latency is high, select larger value for more reliable usage.

 

 

 

 

 

 

 

 

 

 

SIP T2 Interval

 

Maximum retransmission interval for non-INVITE requests and INVITE responses.

 

 

 

 

 

 

 

 

 

 

 

 

DTMF Payload Type

 

Sets the payload type for DTMF using RFC2833.

 

 

 

 

 

 

 

 

 

 

 

Preferred DTMF method

 

The HT502 supports up to 3 different DTMF methods including in-audio, via RTP

 

 

 

 

 

 

(RFC2833) and via Sip Info. The user can configure DTMF method in a priority list.

 

 

 

 

 

 

 

 

 

 

Disable DTMF

 

Default is No. If set to yes, use above DTMF order without negotiation

 

 

 

Negotiation

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

DTMF via RFC2833

 

Send DTMF via RTP (According to RFC 2833).

 

 

 

 

 

 

 

 

 

 

 

 

 

DTMF via SIP INFO

 

Send DTMF via SIP INFO message.

 

 

 

 

 

 

 

 

 

 

 

 

 

Send Flash Event

 

Default is No. If set to yes, flash will be sent as DTMF event.

 

 

 

 

 

 

 

 

 

 

Enable Call Features

 

Default is Yes. (If Yes, call features using star codes will be supported locally)

 

 

 

 

 

 

 

 

 

Offhook Auto-Dial

 

This parameter allows users to configure a User ID or extension number that is

 

 

 

 

 

automatically dialed when off-hook. Only the user part of a SIP address needs is

 

 

 

 

 

entered here. The HT502 will automatically append the “@” and the host portion of the

 

 

 

 

 

corresponding SIP address.

 

 

 

 

 

 

 

 

 

 

Proxy-Require

 

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

 

 

 

 

 

 

 

 

 

 

 

Use NAT IP

 

NAT IP address used in SIP/SDP message. Default is blank.

 

 

 

 

 

 

 

 

 

 

 

Distinctive Ring Tone

 

Custom Ring Tone 1 to 3 with associate Caller ID: when selected, if Caller ID is

 

 

 

 

 

 

configured, then the device will ONLY uses this ring tone when the incoming call is

 

 

 

 

 

from the Caller ID. System Ring Tone is used for all other calls. When selected but no

 

 

 

 

 

Caller ID is configured, the selected ring tone will be used for all incoming calls.

 

 

 

 

 

Distinctive ring tones can be configured not only for matching a whole number, but also

 

 

 

 

 

for matching prefixes. In this case symbol * (star) will be used.

 

 

 

 

 

 

 

For example:

 

 

 

 

 

 

 

if configured as *617, Ring Tone 1 will be used in case of call arrived from the area

 

 

 

 

 

code 617. Any other incoming call will ring using cadence defined in parameter System

 

 

 

 

 

Ring Cadence located under Advanced Settings Configuration page.

 

 

 

 

 

Note: If server supports Alert-Info header and standard ring tone set (Bellcore) or

 

 

 

 

 

distinctive ring tone 1-10 is specified, then the ring tone in the Alert-Info header from

 

 

 

 

 

server will be used. Bellcore rings and tones are independent from custom ring tones.

 

 

 

 

 

The custom ring tones can also be specified by alert-info header, for example

 

 

 

 

 

Alert-Info: <http://127.0.0.1>;info=ring5

 

 

 

 

 

 

 

 

 

 

Disable Call Waiting

 

Default is No. If set to YES Call Waiting indication information will not be provided to

 

 

 

 

 

analog phone connected to this FXS port.

 

 

 

 

 

 

 

 

 

 

 

Disable Call-Waiting

 

Default is No. If set to YES Call Waiting caller ID will not be provided to analog phone

 

 

 

 

Caller ID

 

connected to this FXS port.

 

 

 

 

 

 

 

 

 

 

 

Disable Call Waiting

 

Default is No. This is to disable the stutter Call Waiting Tone when a Call Waiting

 

 

 

Tone

 

information arrives. The CWCID information will still be displayed.

 

 

 

 

 

 

 

 

 

 

Disable Reminder Ring

 

Default is No. Do not play the reminder ring when this is set to Yes.

 

 

 

 

for On-Hold Call

 

 

 

 

 

 

 

 

 

 

 

 

 

Disable Visual MWI

 

If set to “Yes”, the MWI information will not be transferred to the analog phone

 

 

 

 

 

connected to the FXS port.

 

 

 

 

 

 

 

 

 

 

 

Ring Timeout

 

Incoming call will stop ringing when not picked up given a specific period of time.

 

 

 

 

 

 

 

 

 

 

Delayed Call Forward

 

Default value is 20 seconds. In case this feature activated using * codes (*92 code), the

 

 

 

 

Wait Time

 

call will be forwarded after this preconfigured amount of time.

 

 

 

 

 

 

 

 

 

 

 

No Key Entry Timeout

 

Default is 4 seconds. Dialing process is completed and outgoing call is initiated if no

 

 

 

 

 

key entry occurs during this preconfigured interval.

 

 

 

 

 

 

 

 

 

 

 

 

Early Dial

 

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

This parameter controls

 

 

 

 

 

 

whether the phone will 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
