When we create a new Custom Rule under the Call Forwarding and Voicemail section we have an issue where the phone number we enter on the third step of rule creation, Define Call Handling. The number we enter the Forwarding Number box in the Forward to external number radio button will not stay there after we click Save and go back to confirm it is there. So, basically, after we create a rule and we go back and click on Edit to double check everything in the Rule we created the Forwarding Number box is BLANK. However, if we create another rule that conflicts with the rule we just created and hit the Validate Rule button we can see the number when we get the message that we have two rules that conflict with each other. Why would the Forwarding Number be BLANK?
