How can I program the phone to forward incoming calls from main switchboard phone to another extension and have it ring at this phone after not being picked up by main phone after three rings?

It seems like you're trying to configure a phone system or a specific phone to have incoming calls ring on multiple extensions simultaneously or forward to another extension if not answered. The exact steps can vary depending on the phone system or model you're using. If you provide more details about the phone system or model, I can offer more accurate instructions. In the absence of specific information, here's a general guide on how you might achieve this:
**For Most Phone Systems:**
1. **Ring All Extensions:**
- Log in to the phone system's administration interface.
- Locate the call forwarding or call distribution settings.
- Look for options related to "Hunt Group," "Ring Group," "Call Distribution," or similar terms.
- Create a group that includes the extensions you want the incoming calls to ring on.
- Assign the group a number or label.
- Configure incoming calls to be forwarded to the assigned group number or label.
2. **Forward After Rings/No Answer:**
- Within the same settings area, look for options related to "Call Forwarding" or "Follow Me."
- Configure the settings to forward calls to another extension or voicemail after a certain number of rings or if there's no answer.
**Example for Asterisk-based Systems (such as FreePBX):**
1. **Ring All Extensions:**
- Log in to the FreePBX administration interface.
- Create a Ring Group.
- Add the extensions you want to include in the group.
- Set the Ring Strategy to "Ringall" or "Ring All Available."
- Specify the Ring Time (how long it should ring on each extension).
- Save the settings.
2. **Forward After Rings/No Answer:**
- Create a Follow Me setting.
- Add the destination extension(s).
- Set the Ring Time (how many seconds it should ring).
- Configure the Follow Me List to go to the next destination if there's no answer.
- Save the settings.
Please note that terminology and options might differ based on your phone system's manufacturer and model. It's important to consult your phone system's documentation or seek help from your IT department or phone system administrator if you're not familiar with the settings or if you're dealing with a complex setup.
Keep in mind that making changes to a phone system's configuration can impact its functionality, so it's a good practice to do so during non-peak hours or with proper testing to ensure everything works as expected.

What phone system are you using?

KX-TEA/TES/TA series or KX-TDA/TDE/NCP series

Just a guess but maybe changing the connections for the lines on the switchboard. This may also change their numbers though.

You need to know what extension is causing the forward directly to voice mail. Chances are that this extension has ringing lines programmed to it and the forward on busy is to voice mail. ANY PHONE THAT HAS RINGING LINES SHOULD NOT BE SET TO FORWARD ON BUSY. If they happen to be on the phone when a call comes in it will go straight to their personal mailbox.

It takes so long to get an answer because you asked two different and complex questions. 1. Where do you want the call to go? It's related to question #2, but the forward either works or it doesn't...that's what the FWD/DND button is for. Your delay before it goes can ge adjusted. In our installations, we use CF-No Answer and set the ring count to 4. If you're on the phone and another call comes in, you can see it from the display and hear the soft ring. You can either answer it or ignore it and it will go to somewhere else (generally voice mail).

As far as your second question, if you have voice mail, an auto attendant can be part of the system. It's programmed at installaton to pick up incoming calls and follow a menu system called Custom service. It also functions as your voice mail system as mentioned in #1.

Extension call forwarding is controlled by a timer, and they put these things in the manual. If your CF after 2 rings is from a call to a specific extension, from that extension, dial *713 and a 2 digit number from 00-99 seconds on the intercom. Start with 18.

If your call forwarding is from intercept, then you have a system programming issue and need to look in the installer's manual or check with your system programmer.

Someone thought it'd be a good idea for your extension to back up that extension when answsering incoming calls, or their extension is forwarded to yours. Either cancel the call forwarding with the right code (be careful not to remove forwarding to voicemail), or have someone remove the program on your extension which makes you a backup to the other one.

Hello, if you are using this phone on a Panasonic 308 or 824 system press 40 for an external incomming call or 4 followed by the extension number to pick up a certain extension that is ringing.
Thank you.

Ring when? When incoming calls com in to the main number? You would have to get into programming and remove yourself from that group.

If you dont want your phone to ring ever, program a DND button on the phone.

Here is a link to program line ringing.

It sounds like your extension is forwarded (confirmed by the one beep you hear on an incoming call.

From any display phone, press Feature 11
then enter your extension number 2 times. So if you are extension 20, do this:
Feature11-20-20
see if that does it.
