Working with an Express 220 [though this is a cloud-wide issue]. When I dial the system from my cellphone as 1-844-572-5683 and the extension, it dials into the system successfully but it displays on the system as...
example: sip:+firstname.lastname@example.org;isup-oli=0 (sometimes it shows ...;isup-oli=62 or other numbers)
This is what shows up in the redial list also. It seems to be the same when dialing from any phone.
It makes it difficult for a user to go back and see what phone number a call was coming from.
This idea was created form this linked discussion: Telephone participants show as ...@pstn.twilio.com... ?
