Good question! Almost everything goes through the MENU button. To change categories within the menu use the black EDIT arrow buttons at the bottom of the phone just below the number buttons. To select items WITHIN a category, use the silver Review UP/DOWN buttons. And yes, you have to scroll past all the other options to get to the one you need each and every time.

Here is how to navigate that MENU screen:

SKIP TO 13 TO SEE HOW TO SET DATE AND TIME. -- According to Cortelco, the date and time will automatically set the first time you receive a call with a caller ID signal. Customers may not have to set this.

1. [SELECT LANGUAGE] appears on the display. Press REVIEW UP to select the language. ENG - English, ESP - Spanish, FRE - French, and then press MENU to confirm the selection.

2. When [LCD CONTRAST] appears on the display. Press REVIEW UP to select the contrast level. Three levels are available.

3. When [ENTER HOME AREA ] appears, enter the desired area code using the keypad. Use REVIEW UP and REVIEW DOWN to skip a digit. Use REVIEW DOWN to delete a digit. Press MENU to confirm area code. To leave the area code blank, press MENU without entering digits.

4. When [ENTER AREA CODE] appears, enter the desired area code using the keypad. This would be a second area code that is also local. Use REVIEW UP and REVIEW DOWN to skip a digit.

Use REVIEW DOWN to delete a digit. Press MENU to confirm area code. To leave the area code blank, press MENU without entering digits.

5. When [SET ACCESS CODE] appears, enter the desired Access code using the keypad. This is the code that is dialed to access an outside line. Press MENU to confirm the selection.

6. When [SET LDS CODE] appears, enter the desired LDS code using the keypad. Press MENU to confirm the selection.

7. When [FLASH TIMER (MS)] appears, press REVIEW UP to toggle between 600ms, 100 ms, and 300ms. After selecting the desired flash time, press MENU to confirm selection.

8. When [SELECT LINE 1/2?] appears, press 1 to select Line 1 as your primary line or press 2 to select Line 2 as your primary line.

9. When [DIAL MODE] appears, press 1 to select Pulse dialing or press 2 to select Tone dialing.

10. When [VOICEMAIL NUMBER] appears, enter the voicemail number (maximum of 18 digits) using the keypad. To delete a number or digit, press REVIEW DOWN to erase the number(s). After the desired number has been entered, press MENU to confirm selection.

11. When [#3 SEC PAUSES] appears, enter the desired number of pauses using the keypad. After the desired setting has been entered, press MENU to confirm selection.

This can be released at any parallel phone. In PBX mode, the HOLD button dials a code which places a PBX line on hold. If you select PBX mode, see Step 22 to program the code.

20. When [RELEASE MODE] appears on the display. Press REVIEW UP to select either NEWCALL or HANGUP. In NEWCALL mode, the RELEASE button provides a 1.5 second line break. This will ensure that the line is clear and a new call can be dialed. In HANGUP mode, the RELEASE button drops the line, and a new connection is not made. This is primarily intended for programming into speed dial locations.

21. When [SDT TIME] appears on the display, press REVIEW UP to change Stutter Dial Tone timing. Please note that the default setting of 1700 mSec is correct for most applications.

22. When [OFF FIRST RING] appears on the display. Press 1 to suppress the first ring or press 2 to allow it.

Caller ID information is delivered to the phone after the first ring. If this feature is set to YES, Caller ID will appear as the phone begins to ring. If it is set to NO, the phone will ring once, and then Caller ID will appear. Note that if other telephones are connected to the same line, they may ring once before the 2720 if this feature is set to YES.

23. This only applies if you have selected PBX HOLD mode.
