asterisk users - Mar 2007 - mobility with asterisk

Hello,

I?m working testing every feature of asterisk in a lab.  Now I am very
interested in asterisk over network mobility environment. For example : when
somebody is talking with his ip-phone ) and moving around a big enterprise,
needing to change the ip-address (other AP) would it be possible in the
minimum time to avoid loosing quality in the current call? I read this test
http://lists.digium.com/pipermail/asterisk-dev/2006-December/025263.html
but it?was written in December of 2006!! Were this ideas implemented? If you
can help me with information about that please write me and I?ll test and
give you my end result.
Does anybody knows something about which is the best Cisco router to this
mobility environment?

Best regards,

               Pacho

Hi Alvaro,

There was a discussion about this a little while ago. Andrew Joakimsen had
some good ideas with how to allow a wifi sip phone to roam between APs
seemlessly. His post pretty much said the following:

  - Set all APs to the same channel and same SSID.
  - Make sure all APs are connected to the same LAN (no NAT on the AP).
  - Play with the settings on the phone with regards to roaming deltas and
receive levels. Suggested settings:
     - RxLevel: -60
     - PreRoaming: Enable
     - RxLevel: -75
     - Try Over TxErrcnt: 15
     - Try Over RxErrorcnt: 10

Playing with the pre-roaming settings will help you, but you may see a drop
in battery life.

Cheers,
Alex

Take a look at Alberto Pastor's mail on this list at 2007/02/15: moving 
WiFi phone.
