Introduction
Overview
For Series C IP Phones, the Dial Plan and Dial Peer functions can basically meet all user requirements for digit sending and replacement rules. However, new users or those who haven't used these two functions for a long time can hardly complete their configurations via the web interface without referring to the user manual. Even if they learn how to configure by reading the manual, they will forget the steps soon afterward. Therefore, we aim to optimize these two functions to enable users to master configuration directly via the web interface, or at least retain the configuration skills after reading the manual once.
Applicable Models

Dial Out with # Key: Dial the target number and add the # key at the end.
Configure the phone to end digit collection with the # key.
Fixed-Length Dialing: The phone intercepts the input number by the fixed length.
Configure fixed-length digit collection. For example, set to 11 digits: the phone automatically initiates a call with the 11-digit number after the user finishes dialing.
Timeout Dialing: The phone sends the collected digits after the timeout period.
Configure the dialing timeout in seconds. For example, set to 10 seconds: if the user does not dial further digits within 10 seconds after receiving a digit, the phone regards the input as complete and sends the collected digits as the called number.
Blind Transfer with # Suffix
Check this option to perform blind transfer by entering the number in the transfer dial interface and pressing the # key; uncheck to disable blind transfer with the # key.
On-Hook Blind Transfer
Check this option to perform blind transfer by entering the number in the transfer dial interface and hanging up the phone.

Three-Way Conference On-Hook Attended Transfer
Test: The phone establishes a three-way conference with Party B and C. Hang up (hands-free mode: press hands-free key; headset mode: press headset key; handset mode: hang up handset). After hanging up, Party B and C remain connected, realizing attended transfer with mutual number display.

Example 3: Add Prefix
Dial "9312" → send "0079312".
Example 4: Add Suffix
Dial "1383322" → send "13833220088".
Example 5: Delete Prefix
