question

I had the same request as you have David.  Whereas you can have two numbers programmed on an extension, the trick is in making the outbound calls.  Incoming calls are not a problem.  I have one company ring on its own keys and the second company has its own keys.  So, I can answer the incoming call with the proper name.  The trick is outgoing calls since your Outbound Caller ID is based on the device.  (Sidebar, this is true for every Hosted VoIP I tested before picking RC).  What I found is I can program my RC4Windows APP with its own Outbound Caller ID and I make calls for the second company via this APP and that number shows as the Outbound Caller ID.  Another choice was I could use the APP on my cell phone for outbound calls and it works too.  But I prefer the first option.  So in terms of the Outbound Caller ID number it works.  The caveat is displaying the different companys Caller ID name with the number.  After doing this for over a year now, that has not been an issue for me, but I can see where others would want both.  Im sure its a technical hurdle probably tied to anti-spoofing.  Lets see if anyone has any realistic suggestion.
