Yealink W70B keeps ending calls

[engineer5757]

I'm not sure where to post this, as I'm not sure where the actual issue lies. We have a Yealink W70B that keeps ending calls without picking them up. I tried opening a ticket, but can't since this instance is only 4SC. Any ideas? I have reset the phone and re-added to 3CX. Restarted the instance. I'm not sure where else to look. It's a very basic set up. 3 phones, the only Call routing is to ring all 3, and after 20 seconds it goes to a voicemail.

How was the phone provisioned?

This is normal behavior under some conditions. Please check the following

1. Extensions without a handset (or the handset is currently unreachable) will reject your calls.

2. In congested radio environments or when the signal quality (not just strength) is degraded, the base may drop calls.

3. If the above is OK, you may have simply reached the default limit of the base (ie. you have paired more than 5 handsets or sending more calls than the base can handle).

Extend it from here: Features > General Information > Number Of Active Handsets. But a Fair Warning: Yealink sets this as a safe default to 5 for stability and to allow handling of HD codecs in case such a call is received. Please consult the manufacturer to learn what the trade offs are when increasing the base limit.

PS: For these cases where the call is ended by the device its best to open a ticket with Yealink, not 3CX as we cannot tell you why the base made the internal decision to end the call.

It was provisioned behind a Windows 11 SBC. The wireless is always within 15 feet of the base, and it's the only handset paired with the base. I'll reach out to Yealink.
