Hi,
I have been working with Cisco VoIP since 2001 and Asterisk and freepbx ,trixbox, elastix since 2007.
I'm very new to the site so trying to bid as low as possible and get better reviews as much as possible.
That being said, In addition to what you have asked I can offer the following features on Cisco phones :
1) Phone Lock/UnLock.
2) one-to-one and one-to-many Paging.
3) Separate Directories manageable via web.
4) Push-to-Talk.
5) Whisper/Baby monitor.
6) Weather, Stock, Currency and custom reports on Cisco ip phones.
7) on request Caller ID display.
Hope the above is enough to at least start a chat session :)
Regards,
