Update ruined transfer options

When transferring calls the team option is no longer there. You now have to go through a list of every contact saved in the system instead of just having all direct extensions in one place. Super inconvenient and inefficient.

Great user experience (so far)

Been using this app for about 2 weeks now. It is working well and is very easy to use. A lot of features and customization. Would recommend.

Nice...when it works

this app is decent but has a lot of glitches and bugs and doesn't always work properly on my iPhone, it's very frustrating when I missed calls because the app decides to do its own thing
