This is by no means a recommendation, but I just stumbled across a
Grandstream DECT Phone. $75 for a handset + base station and $47 for
additional handsets. I've got a number of stripes on my back from past
adventures with GS, so I would tread warily.

Thanks,

The aastra ct series sets are done. We got word a couple months
ago aastra was dropping all CT series. As a reseller we found the
reception great but batteries terrible. And the feature access
terrible also. Cumbersome at best to transfer a call via hard
transfer. We use native bridging so asterisk transfer was out.
Aastra solution is to try their new solution which is higher
priced of course.

David,
I've used a few of the Gigaset A580's in a small environment where
paging wasn't really an issue. Seemed fine and seemed to be well
constructed.
The one thing that I can confirm is the Aastra DECT handsets that
came with the 57iCT and 480iCT's are best used to hold doors
open. They come with a 12 month warranty but routinely stop
working around 13 months. The batteries are very difficult to
obtain also. It's a product that should just go away.

David,
I've used both the snom m9 and the Panasonic TGP500 a bit. I've
also deployed the Aastra DECT handsets that accompany the [9]480i CT.
the m9 is a small/light handset, not quite cheap feeling, but much
lighter/smaller than the Panasonic (or the Aastra handsets, for
that matter).
the m9 uses a completely different technology base that the snom
deskphones, so don't expect any common-ality between them.
I can't speak completely for the intercom capabilities, but I seem
to recall that you can intercom between the handsets, but not
generically through Asterisk. Also, you cannot dynamically change
the ring tone using the SIP Headers approach. They have expressed
a desire to do so, but that was two years ago on the m3.
I have had some troubles in some situations with getting the snom
m9 to work reliably with certain routers. It's a mystery why it
works in some cases and not others, but the phone has a bit of a
tendency to lose registration and just sit there. A reboot always
helps. I have deployed the Panasonic in some cases where the m9
doesn't play well.
That being said, the Panasonic uses a *completely* different
registration methodology than your typical SIP Phone. A typical
SIP phone will be configured to resend a registration ever so
often, and, if so configured, asterisk will send down options
packets every so often. This keeps the port path through the
router open and fresh.
The Panasonic TGP family sends ONE registration at the dawn of
time, and sends 42 byte SIP heartbeats every 30-90 seconds, for
which there are no responses either defined or expected. Many
times if these packets don't reach the asterisk pbx, the phone is
blissfully unaware and will still say it is registered. It's
ironic that I started using the Panasonic as a stop-gap for the
m9... I currently have a semi-large installation where the
customer acquired a bunch of TGP550's (handset + deskset), and
after some period of time: could be days, weeks, months, the phone
just decides to stop sending the heartbeat, and, 90 seconds later
the router closes the path, and the phone has to be rebooted. I
do have the attention of a 2nd/3rd level support tech within
Panasonic looking at pcap files regarding this, but my confidence
level is not high at present that it will be resolved in my lifetime.
Some users like the m9 handset because it is light and small.
Others like the meatier Panasonic or Aastra. Personal preference.
Hope this helps,
Ron

Does anyone have any experience with wireless DECT phones for
VoIP / Asterisk. A google search has turned up Snom M9r,
Siemens Gigaset A580 IP, Panasonic KX-TGP500. The Gigaset is
significantly cheaper than the other two but I can't find a
good review/comparison of them all. One feature that I would
want to use in the future, though maybe not initially, is
intercom/paging... which means support for additional SIP
header with answer-after=0 appended. It is not clear whether
any of them will work with this, the only documentation I can
find suggests that the Snom might work... but only if it is
told that the IP PBX is the Snom ONE.
Thoughts, or other alternatives.
