If you have access to the backend GUI - it's under Settings / SIP / Digitmap Timeout - there's a second count for each of the Digitmappings directly above. We found 4 to be too long, and have impatient users, and set ours to 2 seconds for each.

should look like:

3|3|3|3|3

for as many mappings you have. The 'pipe' is the shifted character above the Enter key. ( | )

Hope that helps.

I logged into the GUI of the T48S and am not seeing that Digitmap Timeout option. Under SIP, all I have is a few SIP session Timers and a couple of SIP Ports.

Well, don't I feel sheepish - I was provisioning a Polycom when I saw the message and just switched screens... If you're ever on a Polycom - that's where that setting is.

Yealink: Under the Settings / Preferences tab:

Let me know.

No worries. It's been one of those weeks for me as well. :)

I did find that setting and changed it to 10s with both the 'Live Dialpad' option enabled and disabled. Unfortunately, that didn't help. It's still autodialing if I pause more than ~1.5 seconds when typing in a number.

Maybe with this being a RingCentral phone, they did something to the firmware to ignore those settings?

Check my comments above. It was user error opening a line and expecting the phone to know not to dial out.

If you hear a dial tone you can expect it to dial out as soon as a pause (2 sec) occurs no matter what setting is applied.
