I have an MCD 5.0 and MBG server 7.1. Customer wants a way to use their iPhones as softphones when they are out o the office. My question is if they install the Bria softphone APP on their iPhones, do I build an extension for the iPhone as a generic SIP device in both the MCD and in the MBG. Can I point the Bria softphone APP to the public IP of the MBG? Will it be able to connect throuh the MBG to the MCD?

Thanks!
