Who is this Guide For?
- All Crexendo end users using a desk phone
Prerequisites
- A provisioned Crexendo desk phone and an active extension
- Basic familiarity with your phone’s keypad, handset, and speaker
- (Optional) Your organization’s call park extensions (typically in the 9000 range)
Overview
Crexendo supports multiple desk phone models, but the core call-handling features are consistent across devices. This guide covers the most common day-to-day scenarios: answering calls, making calls, transferring, holding, conferencing, call parking, and a quick reference for star codes (feature codes).
Key Terms and Buttons
- Line/Feature Buttons: The first buttons on the left side are typically your phone lines (used to manage multiple calls). Other buttons may be programmed for features like Speed Dials, Park buttons, or BLF keys (busy lamp field/status).
- Soft Keys: Buttons whose functions change depending on what the phone is doing.
- Hard Keys: Buttons that stay the same (navigation, volume, headset, voicemail, mute, hold, redial, transfer, speakerphone, etc.).
Soft key examples:
- Idle: History, Directory, Do Not Disturb, Menu
- Handset picked up: Directory, 123, Cancel
- Dialing: Send, 123, Delete, Cancel
- On a call: Transfer, Hold, Conference, End Call

Common Call Scenarios
Answering a Call
When you are not on another call:
- Lift the handset (or press Speaker/Headset if applicable).
When you are already on a call:
- Press the Answer soft key (or press the flashing line button for the incoming call).
- Your original call is placed on hold automatically.
- To switch between calls, press the corresponding line/feature button for the call you want to speak with.
Tip: Soft keys change based on what you’re doing. If you don’t see “Answer,” look for a flashing line key or a call appearance button.
Making a Call
Internal call:
- Lift the handset.
- Dial the extension.
- Press Send (or wait if your phone auto-dials).
External call:
- Lift the handset (or press Speaker).
- Dial the 10-digit number.
- Press Send or wait ~4 seconds for the system to dial automatically (varies by model/config).
Transferring a Call
There are two common transfer types: Attended (consult first) and Unattended (blind transfer).
Attended Transfer:
- While on the call, press Transfer (soft key or hard key).
- Dial the extension or phone number, then press Send.
- Announce the call and confirm they can take it.
- Press Transfer again to complete the transfer (hanging up may also complete it, depending on model/config).
If they cannot take the call:
- End the consult leg (often End Call soft key).
- Press the original caller’s line key to return to them (they are still on hold).
Unattended Transfer (blind):
- Press Transfer.
- Dial the extension or phone number.
- Press Transfer again to complete.
Hold Function
Place a call on hold:
- Press Hold (soft key or hard key) during an active call.
- The line will typically flash to indicate the call is on hold.
Resume a call on hold:
- Press the flashing line/hold key for the call, or press Resume if shown.
Conference Call (Up to 3 People)
- During an active call, press Conference. The active call is placed on hold.
- Dial the second party’s extension/number and press Send.
- When they answer, press Conference again to join all parties.
Park Function (Call Park)
Call Park places a call into a shared “hold queue” so another user can pick it up (instead of transferring it directly). Call parks must be created by an administrator. They are commonly in the 9000 range (e.g., Park 1 = 9001, Park 2 = 9002).
Park a call (using transfer):
- While on the call, press Transfer (soft key or hard key). The caller is placed on hold.
- Dial the Call Park extension (example: 9001).
- Press B. Transfer or press Transfer again (depends on model).
- The call is now parked on that Call Park.
Park a call (if you have a Park button programmed):
- During the call, press the programmed Park feature button.
- The phone parks the call immediately to that park location.
Retrieve a parked call:
- Dial the Call Park extension (example: 9001) and press Send (or wait ~4 seconds).
- If you have the park programmed as a button, you can often just press the Park button to retrieve.
Phone Feature Codes (Star Codes)
Feature codes or star codes are shortcuts you can dial from a desk phone (and in many cases web phone/mobile) to perform common actions. Availability can vary by configuration and permissions.

Troubleshooting
I can’t complete a transfer
- Try an Attended transfer first (consult, then transfer).
- If the call won’t release, press End Call on the consult leg and return to the original caller’s line key.
- If transferring to voicemail fails, confirm your environment supports the voicemail transfer code and that you have permission.
Call Park isn’t working
- Confirm you are dialing the correct park extension (often 9001, 9002, etc.).
- Call Parks must be created by an administrator—if no parks exist, parking will fail.
- If using a programmed park button, confirm it’s assigned to the correct park location.
A star code doesn’t work
- Some star codes require permissions (monitoring, recording, call center agent codes).
- Try pressing [SEND] after dialing the code (some phones won’t auto-send star codes).
- Codes can vary by configuration—if you suspect a mismatch, contact support.
FAQ
What’s the difference between Hold and Park?
Hold keeps the call on your phone only. Park places the call into a shared spot so another user can retrieve it.
Why don’t my soft keys match what’s shown here?
Soft keys change by phone model and what your phone is doing (idle vs. active call vs. ringing). Use the closest equivalent (Answer/Transfer/Hold/Conference) or your line keys.
Can I conference more than 3 people?
Many desk phones support a 3-party conference using the Conference key. Larger conferences typically require a conference bridge or a separate conferencing feature.
