First off, let’s describe the technology built into the Siemens Gigaset A580IP as well as its capabilities from a hardware perspective. The Siemens Gigaset A580 IP is a DECT 6.0 cordless handset which comes with a cordless handset, charging desktop docking station, DECT base unit, and power adapters. The cordless handset simply pairs to the DECT base unit much like your traditional analog cordless phones do (actually a similar technology @ 1.9 GHz) or your mobile Bluetooth headset would.

Here is where the DECT Gigaset A580IP differs from your traditional analog cordless phone; the base unit has both an analog RJ-11 port to connect your existing landline in (POTS/ PSTN), and also an RJ-45 LAN Ethernet port to plug into your IP network to support VoIP service. The base has the ability, if you configure it to, to perform auto-PSTN fall back or failover. What this means is that if you have a VOIP service or are connected to your organization’s IP PBX via SIP, and your IP connection or Internet goes down, the Gigaset will automatically route calls through your landline connection plugged into the back of the DECT base unit. Pretty effective if you are one of those people that needs to make and receive calls 24/7.

The DECT base unit has the ability to support up to 6 different cordless handsets and each can be configured as an individual SIP VOIP account. Pretty cool for a small office setup!! Please note that the product ships with only 1 handset and you can purchase up to 5 additional handsets to add on.

If you are used to IP web GUI based configurations, the Gigaset A580 IP is right up your alley as you can easily browse to its LAN DHCP fed IP address from any computer on the same LAN by simply typing its IP address in your web browser address bar.

Here are some of the first-look highlights and configurations I have performed on the A580IP:

  • -Has the ability to configure up to 6 SIP VOIP accounts (I have configured 2, one for my lab Trixbox, and the other on our production Switchvox SMB. (Click Image Below for Expanded Screenshot)

  • -Easy to setup SIP registrations: (Setup for Trixbox account) (Click Image Below for Expanded Screenshot)

  • -VoIP Provider auto-configuration (auto-provisioning support)
  • -Configurable auto-PSTN fall back or failover (This is discussed above). Configurable incoming and outgoing call rules specific to the SIP VOIP connections or PSTN Landline connections. (Click Image Below for Expanded Screenshot)

  • -Configurable Dial plans for cost based routing. (Click Image Below for Expanded Screenshot)

  • -Configurable VM boxes for each SIP VOIP account (Click Image Below for Expanded Screenshot)

  • -Configurable Audio codec’s per each SIP VoIP account in cases where there may be a small amount of bandwidth (G.729 codec) or to experience HD Voice (G.722) HD endpoint to HD endpoint only. Call VoIP Supply for a complete listing of HD IP Phones. (Click Image Below for Expanded Screenshot)

    This looks like a nice phone for a reasonable price. I see that there is pricing for basestation+handset. What about additional handsets? I can’t see any listed on your site.

  2. Jay,

    The technology is pretty much the same. Both the Siemens and M3 broadcast wireless connectivity over DECT. The complete system allows up to 8 handsets to pair to one base DECT AP. The Siemens does however allow connectivity to the PSTN through its RJ-11 jack on the base, where the M3 only has SIP connectability. This is a very nice feature if the network goes down, the Siemens fails over to PSTN connectivity for seemless failover. In my personal experince, both the M3 and Siemens handsets are very well performing wireless VOIP handsets. You may also want to look at the Siemens S675 IP as well:

  3. This looks like a nice phone. I’m pretty new to VOIP and I’ve been using a normal phone with an ATA adapter. The adapter has stopped working however and I’ve decided to get a VOIP phone instead. Will i need to get a new adapter with this phone, or can I plug it straight into my modem?

      There is no need to buy an adapter with the Gigaset A580. All you need to do is connect it to your home modem, router or switch.

  4. With either of these phones, can you set up multiple handsets to work on one SIP account/seat. Most DECT systems made for PSTN lines share one line/extension with many wireless handsets. We are looking for a similar functionality for a VOIP phone. It would basically be used for a home phone, we want multiple handsets that share one line/extension. Rather then each handset having it’s own SIP account, as this is cost prohibitive for a simple home phone usage.

    Thanks,

    Greg

      Each unit supports up to six additional handsets. All of the handsets can be configured to work with a single SIP account and ring simultaneously when the number associated with the SIP account is called.

  5. We have been using the 580i for about two months ( 6 handsets ) and find it a perfect solution to our needs. We answer the phone 24 X 7 and whomever is on duty has a handset. Range is good as we can cover our entire 9 acres without loss of coverage.

    We would like to see the Repeater unit that is offered in the EU go on sale here. With the Repeater we could increase our range to cover an adjacent piece of property.

    I asked our Gigaset Representative if the EU version would ever come over to the states. He replied that there is no DECT repeater that Gigaset manufacturers to accompany the A580 IP or S675 IP in the US, but did hint that the Snom M3 DECT repeater may work as he has heard users using this repeater with their Gigaset setups. There is no 100 percent confirmation on this however. In theory, it should work, DECT signalling is standard across the board. If you want to try it out, they are fairly cheap and can be found here:

  7. I just hooked up one of these to my Trixbox. I have it receiving calls and dialing internal extensions fine. I can’t seem to get it to dial outside?

  8. I create one extension on TrixBox CE server;
    Register that extension on Gigaset A580IP configuration “Settings > Telephony >Connections”. Status: Registered.
    Then, when I’m trying to make calls from other extension to this extension doesn’t work.

    I can make calls from other extensions, making calls using TrixBox “Outbound routes” to use different VOIP accounts, and it works fine.

    Can anyone help me with this problem?

  9. Hi,

    I’m just wondering if this system can be configured to work with Asterisk and if each handset can be a different extension using on single VOIP account.

    Thanks in advance,

  10. GZ,

    Each handset can be configured as a different unique SIP extension to a single asterisk server. It has been tested and fully functional with Asterisk.

  11. Hi,
    I have a trixbox C.E 2.6, with Asterisk 1.4 but having trouble with my New Gigaset A580IP. Previously I’ve had a Snom M3 working fine, but after the handset fell on the floor it broke, so I bought this Gigaset to replace it.
    I can with no problems call to the Gigaset, audio perfect, but when calling out of the house, there is no audio in the handset, the one I’m calling can hear me, but I can’t hear the other end. I’ve got other Gigaset handsets on the base, and the issue is the same. Calling internally to other extensions the audio is perfect both in and out.
    Any help would be very much appreciated.

    Regards

  12. I am very new to the Voip system and am trying to find the best phone with least amount of hardware. We have 3 voip phone lines. Is it possible to have all three lines ring on each phone? will the display distinguish the calls from each voip line? The reason I ask is that 1 voip line is our home number and the 2 other numbers are separate business lines. But I don’t want to have a million handsets around the house…LOL.. to easy to misplace.

    One phone upstairs, one downstairs and one in garage would be perfect. Even more so if I could distinguish who’s call (home, business#1 or business#2) is coming in so I can answer the phone appropriately. Or does each voip line have to have its own phone in which case I would have 3 upstairs, 3 down and 3 in garage???

    Any assistance would be greatly appreciated. Thank you.

  13. I need 8 handsets, then I bought two Gigaset 675 bases and another six handsets. I thought that I would be able to configure the phones and the bases to call each other, i.e. used them as a PABX system. However, the only thing I manage to do is to call from one handset (in one base) to another handset in the SAME BASE. I also manage to call the other base (all handset in the base ring) just typing the IP number of that base change the “.” by “*” (the dot by asterix). Has anybody any idea how to configure the bases as a PABX system? Is this possible? Thanks in advance. Julio
