Heya list, I need some advice/experience. Some of our customers are asking us about DECT solutions for their asterisk install. Some others will not go to asterisk if there won't be a DECT solution. They now have a Siemens or a Samsung PBX. Those PBX-es come with a DECT basestation and optionally repeaters etc. All those basestations speak some own protocol to the PBX, so we cannot use them with asterisk. I been looking around on the internet and found the Kirk gear. Anyone has any experience with them ? The website states they are recognized as Cisco 7970 in CCM. Does chan-sccp handel those Kirk emulated devices ? Is there any other solution like this out there that works with asterisk ?

I want something for the house here, at the moment I just have 2 analog dect bases plugged into the same line, but you cant roam between them so if I want to walk from one end of the section to the other I have to park the call, change base station and pick it up again, and then also multi handset doesnt work between bases etc etc. I would ideally like a dect network that plugs into the lan and then the handsets each register as an individual sip extension regardless of what base they are on at the time. I could really use a couple more bases around the place here to get good coverage. -------------- next part -------------- A non-text attachment was scrubbed...

Yep wifi doesn't do base to base roaming, stick with dect for the next 12-18 months until wifi gets it's act together. You might also like to check out Nira (or ascom nira) as they have a standalone dect solution if you are looking to rollout a truly large system for a manufacturing/warehouse (hell I've seen an ericsson md110 being used as a standalone for 1 installation (a little over 40 million square feet of coverage with 300 handsets) but I somehow don't think this is the league you are talking about). Cheers, Dean p.s. yes I know that there are 2 wifi base to base roaming solutions available but they are dammed expensive for what you are getting and dect is a perfectly good solution for today.> -----Original Message----- > From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users- > bounces@lists.digium.com] On Behalf Of Michiel van Baak > Sent: Wednesday, 17 August 2005 2:51 PM > To: asterisk-users@lists.digium.com > Subject: Re: [Asterisk-Users] DECT gateways > > On 20:42, Wed 17 Aug 05, Yoann Le Bihan wrote: > > 2005/8/17, Michiel van Baak <michiel@vanbaak.info>: > > > Is there any other solution like this out there that works > > > with asterisk ? > > > > Why don't you use WiFi VoIP phones like ZyXEL 2000W (which is notsuch> > expensive compared with Cisco ones...) ? > > > > Best regards, > > > > There are no cisco phones involved.

Why don't you use the existing PBX and connect it to Asterisk via S2M? I'm running a DECT PBX myself and it has a "sub-PBX" feature. In that mode it will act as a gateway between ISDN (Asterisk) and the DECT phones. So if you dial 1234 on a DECT phone, it will first check if there is a DECT extension with number 1234 assigned to it. If there isn't, it calls 1234 on the ISDN line. For me, that's exactly what I need to interconnect DECT phones and Asterisk. Andreas

Does > chan-sccp handel those Kirk emulated devices ?Hi Michiel, I have a Kirk set which should be able to do H323, but I haven't had time yet to try it. They have SCCP and H323 types, and ofcourse there are sets which can be connected via an E1 link. If you have time I'm sure we can figure it out :-) Florian
Hi! I have the Kirk IP600, technically it's great and *the* best solution for wireless phones and VOIP. WiFi phones plainly suck for a dozen of reasons and IMHO are totally useless. However, here comes the bad part. Currently you need to use the chan_sccp driver to talk to it and that is not the most stable driver. I'm still battling to get it to work properly using 4 phones. Kirk (sold as Tiptel in NL) is rumoured to support standard SIP, the firmware was due to be released right about now. Haven't heard anything from Kirk support on this however and the last thing I heard was that they still had to start working on it in July. But that's just rumours. Cheers!

What might seem like overkill could be mandated by liftcages, firestairs etc. Also if you want to add dect coverage in a busy area where lots of people with dect handsets gather (meeting rooms, canteens) you need lots of basestations. I've worked in a building where there seemed to be an overkill of basestations every hallway had 3 or 4, (every 20 meters or so) and still there were areas with insufficient coverage... -- Andreas Sikkema bbned NV Van Vollenhovenstraat 3 3016 BE Rotterdam t: +31 (0)10 2245544 f: +31 (0)10 413 65 45
Wow that is overkill (3 bases every 20 meters) could have/should have been better planned for by use of overlapping cells covering not only office but walkway areas as well. The most I've ever seen is 8 base stations stacked 1 on top of the other on a trading platform where all of the dealers/traders used headset based dect handsets.
