Professional SIP DECT plant - VoIP General, VoIP News, VoIP Providers, VoIP hardware, VoIP software, VoIP Technology

I am on the search for a professional SIP DECT plant. Which can recommend you for smaller to middle enterprises.
Rough data:
- ~20-50 mobile parts (depending upon size of the UN)
- Roaming
- Handover
- SIP (is to run at Asterisk)
- ~5-20 paralle discussions (depending upon size of the UN)
- Price only times unimportant

Greetings

- Polycom/Kirk IP600/3 and/or. IP6000 - depending upon requirement profile
- Aastra DeTeWe RFP L32 IP

OK ONE, thanks.
Someone knows those BSIP1 by Siemens Enterprise - experiences. If one the guidance does not look at oneself wants one those to really configure. Is the Kirk/Aastra Basen to be furnished also so complicated/time-consuming?

Which is called complicated?! Clearly, Sip is actually already more complicated, because alone the network causes behind it already expenditure and then the Syncronisation of the Basen, so that Handover goes. All this goes to DECT transmitter with a classical solution, thus over Up0, many more simply and is not not so error-prone.

One must have something experience with DECT, but ansich the Aastra and Kirk solution are to be taken problem-free in enterprise. The Siemens solution was originally developed by IKON. A question would be also which hand sets you to take wants (manufacturer-specifically or GAP/CAP).

@ahnungslos99: all DECT systems over IP admitted to me have by the way with the Handover and/or. Sync at all no problem, (have over 15 years DECT systems - classical and over IP - installed). By the connection over IP one is IMHO more flexibly than over (prop. guessing acres) systems with Up0.

There I am however curious, as functions then with other manufacturers. Over IP syncronisieren might become difficult, because of different running times. That cannot present to me so quite. I thought so far that the Basen always syncron was must (wg. Time slots), so that a Handover folds perfectly. Let me however gladly somewhat better beleheren.

EDIT: Wikipedia lists also still different gentleman plates:

For enterprise use the following vendors produce IP-DECT of system:

- Aastra (DeTeWe)

- Ascom

- Polycom (Kirk)

- Philips

The Sync been made by transmit-strains; the cells must overlap themselves therefore differently than with TK-plants with integrated DECT something. The IKON solution becomes as per. Developers one first a Sync also over IP offer - the empirical values are missing to me however there also.

I did not see the solutions of Ascom and Philips/NEC so far yet anywhere and/or. anywhere to ago refer cannot. Information to the systems of the two manufacturers is also rather meager.

In addition a contribution on the latter is interesting amoocon, here by Siemens the release of open steam turbine and gas turbine systems telephones for Asterisk is communicated, in addition the BSIP1 is to be seen in this connection. It is implied that this DECT solution is released also for Asterisk/is…

There is “DECT coding located supported”, is called that those can that force or only as option after free choice clients operate in the data sheet?

The Kirk of models do not find I under the type designation.

more @VoIPMaster,

I have here a project with very similar requirements.

DECT system for binding to a SIP TK plant. Approx. 50 antennas distributes on 9 buildings and 3 locations.

With Aastra I read that the antennas must always have Funkkontakt to their neighbour around itself to synchronize. That would actually be for us an exclusion criterion.

I wanted to inquire times whether your project was in the meantime converted and whether I might contact you reference exchange of experience?

Many greetings

With the Aastra system one can activate the coding and deactivate IMHO in a coming firmware also device-related.

With the DEK ton en IP systems of Polycom, Aastra DeTeWe and Siemens must overlap themselves the radio cells, in order to make the synchronization available of the overall system.

With the system of Siemens is planned in a future version to make the Sync by IP (if I the developer still correctly in the back of the head have). But is the Siemens system z.Zt. not been suitable from the structure (number of cells) for your requirements.

Here it comes on the spatial distribution of the buildings/locations over to plan on whether it is realizable with a DEK ton en IP system or with one anderern one DECT system.
