Cisco Call Manager users?

The Cisco controller based Wireless AP's all support the handoff features allowing seemless roaming between AP's without dropping calls (for VoWlan specifically). I dont know the exact spec on the handoff feature - I know its good enough to support VoIP which is pretty touchly with latency and loss ;-)
 
Ubiquiti makes nice stuff though - certainly a great value for what it is. I like using them in small biz and large homes. I wish the regular UAPs were standard POE though... thats about the only complaint I've had. The controller software should install as a service (I know they have a process/hack to get it setup).
 
Keep in mind when stress tested against industry standard AP's Ubiquity placed last..

when used appropriately its a sub $100 Access point thats pretty sweet :-) and to be fair they were testing against accesspoints that are 3-4 times as expensive.
 
I agree with all that... it is a little cheezy to have to buy the adapters if you want to incorporate them on 802.3af; but their solution is a lot cheaper when you are deploying where that infrastructure is not in place (vs. buying a ton of single port POE injectors). 
 
CUCM is pretty powerfull, like "whatuusay1" said you can work with SIP Trunk, it just doesn't support authentication... You have to use IP auth with your provider (Voip.ms support it, using sub account).  At home I use CUCM for my personnal DID, but I also receive calls from other DID, but they ring "Silently" on my phone and when I miss a call it doesn't show anything about a missed call, so if I want I can answer a call designated to someone else in my house but never get annoyed by it haha.
 
Also CUCM support Sip endpoint (SIP Phone) I also use an old linksys SPA525 and it work perfectly.
 
Ps : Work2Play for your nat problems, just use Nat KeepAlive!
 
Finally my CCIE cert is useful!
 
The newer CUCM versions (9.x specifically) allow for 3rd party SIP endpoints as well as trunks.  Even the ancient versions of CCM (4.x) had some SIP features for trunking but they were really, really kludgy.  You could also get a copy of Cisco's massive SIP proxy, the "intercompany media engine".
 
The only way to get handoff with the Cisco APs is to have a WiFi controller pulling the strings behind the curtain, and is essential for 802.11e quality of service (so your laptop or iPad streaming Netflix doesn't drown out your phone call).  I have a Ubiquity MiFi AP here at the house, I don't really know how it will work for roaming until I add a second AP when I build the new shop/garage.
 
For a house, unless you really want some crazy features, CUCME on a router is the way to go... but then you have to pony up for that.  Plus now with IOS 15 they are enforcing IOS licensing pretty strictly, no more just installing the IOS you want and running it.
 
Really, in the end... these are big enterprise products, and are massive overkill to run a few phones at the house.
 
Your ubiquiti APs will handle handoff quite nicely once you upgrade to Unifi 3.0 - it has some great new technology for zero-handoff.
 
These won't work with the Cisco system, but I really like the http://www.grandstream.com/index.php/products/ip-voice-telephony/enterprise-ip-phones/gxp2200]Grandstream GPX-2200 SIP phone with Android[/url].  You can run any Android app that you like, it integrates with your contacts (Outlook, Google, etc) so you don't have to keep a separate phone book, and it has a lot of features like built in bluetooth and available wireless dongle and usb cameras.  It also uses the HD Voice technology, so the call quality (even on speaker phone) is excellent.
 
I like it because I can run the CQC Android interface on it and design screens to control any aspect of my automation system via the touch screen.  I also like using the intercom feature of the phone system (I'm running PBF in a Flash) which allows me to ring any extension (or groups of extensions - like the whole house) and have the phones set up where they will auto answer with the speaker phone for any intercom connection.  That way the people I'm trying to communicate with (usually the kids) don't have to pick up the phone to talk back.  We have two way communication through the speaker phone. 
 
Very nice sic - I've been meaning to set up that same type of intercom system for the kids.
 
As far as grandstream on Cisco - it really depends on if your cisco system is set up to handle SIP extensions or not.  I believe some of the small business ones may not do it, but the full blown UCM certainly does. 
 
I've played with a few VOIP varieties at home - including 3CX, FreePBX, Asterisk, etc - and at one point had a fully [well] functioning PlugPBX - I think I want to redo it one more time to support video then I'll do the intercoms and front door cam...
 
Another related fun product - grandstream cameras support SIP so you can call them and talk to people or have them call you upon alarm or motion trip...  looking forward to integrating some of them as well.

The intercom feature is really nice.  You just want to make sure that whatever phone you use has an "auto answer" option.  Some SIP phones do not and therefore the intercom feature isn't as nice because the person being called must pick up the phone to communicate.  My parents have an intercom system in their house, but again a user must press a button to speak into it which makes it less convenient to use - you can't just answer the person back, but you must stop what you are doing and walk over to the wall mounted intercom box to speak.  This is why I really like the auto answer ability that the phone system offers.  Our house isn't that big, but it is three stories and we found ourselves yelling up and down the stairs to call the family to a meal, or get the kids to do something, etc, etc, etc.  The intercom works so much better for these things.
 
I wasn't aware that the Grandstream cameras supported SIP.  That would be great if you could incorporate two way SIP communication through the camera!  I'll certainly have to look into this more.  
 
Are there any of these fancy phones that are wireless (no basestation)?  Like a wireless Android SIP phone?

You can get get desk phones which have a wireless ethernet connection for SIP communications.  You can get DTEC wireless SIP phones that have a base station somewhere that they connect to. But yes, they also make wi-fi SIP phones which are wireless without a base station.  I've heard generally bad reports about the wi-fi phones however and therefore they would be on the bottom of my list as far as phone options are concerned.
 
You can do Wifi SIP phones if you want... the reason people have had issues is if they don't have the right equipment and configuration to support some amount of QoS - I've done it in an enterprise environment so I know it's pretty doable; and I used to use the Cisco SCCP wifi phones at home with good success.
 
The DECT phones are an interesting breed in that they are like mini phone systems with phone to phone intercom and they work together a bit.  I use a cheap SNOM which works fine but I need to test some more.  They're nice in that they don't use your wifi so it doesn't require you to set anything up special
