Do you have an extension “+16023627646”? If not, that’s why.

That’s the DID

You have an inbound route configured which points to a specific destination?

5

yes it point to an ext on cucm. It works most of the time but I have notice that 1 out of 10 calls will fail

6

Is that the DID you specified in the Inbound Route, or are you using an “Any/Any” route? If you are only specifying the exact DID, you might want an default inbound route to capture any variants that might come in.

attached is the route. I place 5 call from the same number and one failed.

Route
Route1812×581 14.9 KB

Get rid of the DID number. If it’s your only phone number, this route would then be used for everything.

Maybe it’s an error on the cucm side of things. Have you checked that out?

I have not yet. was going from the trunk in, on my troubleshooting. Twilio told me that the calls wee being return with a 404 error so that’s why I started my troubleshooting in the asterisk\PBX side
