I am new to this device and am attempting to get my first R201 to work with my VoIP provider. Currently they only support Grandstream 5XX/7XX/8XX and Cisco 11X ATA's. I have managed to get the R201 registered and can receive calls but cannot get outbound to work. CDR captures show that the call attempt is made but that the SIP provider fails the call attempt. Similar attempts using a GS501 process fine.
I am on the current rev of software for the R201 and am wondering if anyone has a config template that is similar to the above devices that could be pushed to get outbound functioning.

Any help would be appreciated
