I still feel like I've only scratched the surface here - I think that with a little thought and effort you could do a lot of creative things with these units, given that you can route calls from one service to any other service (or even do "hairpin turns" on the same service - see the comments section under Part 4). The more people that get their hands on these units, the more I think we will see them put to clever and creative uses.
Just checking to see if anybody tried OBI110 with Vonage using its call transfer feature to make parallel calls without holding the Vonage line.
