I was doing some diagnostics - calling from my cell phone to one of our DID's and I came across this field with this in it.. P-Charge-Info: tel:602?????26 (masking the number as it seems like someones phone numbers - but none of ours in 3cx) Is this a phone number? What exactly is this field for? to add to this - my phone shows the first call came from the 602 number. When I called again 2 minutes later, it showed as my cell phone.
