At the moment I have my phone set to show the main company line when I call out, and my internal extension when I call someone in the company. Everyone in the company is set up this way. The problem is that I would like to make custom rules for the company numbers, but the custom rules doesn't allow for the entry of extensions. It seems that it only connects with my personal contacts and not with the company contacts.
This is pretty annoying, and means that I either need to let my direct dial number show to the public (which is not ideal for a number of reasons), or I have to drop the internal extension setting, which will mean when I call other internal numbers all they will see is the company main line, instead of knowing who in the company is calling them.
I think this could be fixed by allowing the custom rules to access the Company phone book, or by allowing for the entry of extensions in format Ext. ##
Or, as I suggested elsewhere, just allowing the custom rules to distinguish between internal and external callers would solve the issue as well.
