Gigaset SIP/DECT Handsets For 2010: Part 6 – SL78H

Introduced in early 2009, the Gigaset SL78H is the top-of-the-line cordless handset that they offer in North America.

Like the C59H and S79H, the SL78H is only being offered as an expansion handset with respect to the IP-capable A580IP and S675IP systems. You may see it offered as part of the SL780 or SL785, but these are not IP-capable systems.

As I’ve moved up the product range there has been a natural progression in features and physical attributes. Each better model builds logically upon the previous, but adds certain improvements in hardware or software.

At the top of the range the SL78H is physically a very different device. To start, it’s heavy. Unlike the prior models there is a lot of metal in the SL78H. Even the keypad itself has a brushed-metallic finish.

Gigaset SIP/DECT Handsets For 2010: Part 5 – S79H

Thus far in this series I’ve looked at things common to all the Gigaset handsetsthe A58HC59H and S67H. This time I’m examining the S79H.

The S79H has actually become my favorite of the five Gigaset handsets that I’ve tried. My challenge now is to describe how it came to earn that honor.

You may look around and find it offered as part of the S790 or S795 DECT systems. These include a DECT base that provide only an analog line interface and are not SIP capable.

Like the C59H, the S79H is only being offered in North America as an expansion handset. It can be used in conjunction with any existing A580IP or S675IP system.

USB & Bluetooth In IP Phones: A Missed Opportunity?

Last week’s VUC call with FWDs Dan Behringer brings to mind a common complaint about SIP desk phones, namely the lack of an alphanumeric keyboard. Lacking a proper keyboard it’s difficult to really push the idea of SIP URIs as a primary means of making calls.

There are a variety of approaches to overcoming this, including the use of ISNs as prescribed by the Freenum project. That project proposes a means of dialing SIP URIs indirectly, assigning them ISN numbers. Since ISNs use only numbers and the * key they can be dialed on a traditional phone keypad. It’s essentially a way of avoiding SIP URIs through indirection.

Gigaset SIP/DECT Handsets For 2010: Part 4 – S67H

Thus far in this series I’ve looked at things common to all the Gigaset handsets, the A58H and C59H. With this post I turn my gaze to the middle-of-the range S67H.

Since there are already some good reviews of the S675IP available online I’m not going to go into great length describing it here. However, I will highlight the differences between it and it’s siblings in the Gigaset range.

To start I recommend you read the review offered by Alan Lord at The Open Sourcer.com. In his review Mr. Lord details his use of the S685IP with an Asterisk system. His review has been online for a while and collected a long comment trail with a lot of good information.

Gigaset SIP/DECT Handsets For 2010: Part 3 – C59H

Thus far in this series I’ve looked at things common to all the Gigaset handsets and the entry level A58H. With this post I move up the product line one step to focus on the C59H handset.

Newly offered for 2010 the C59H is a significant step up from the A58H described previously. Listing for just $10 more than the A58H, I suspect that many people will find the C59H worth the added cost.

With respect to the A580IP and S675IP the C59H is being offered only as an optional expansion handset. You must have one of the two IP capable systems, then you can add the C59H if desired.

Within the Gigaset SIP/DECT product range the IP enabled base systems are clearly indicated with an “IP” model designation. You may also see Gigaset offering a model C590, if not in the US at least in other parts of the world. The C590 is a complete system comprised of a DECT base and one C59H handset. However, the DECT base in question is not IP capable. It does not have a network connector, only the analog line interface.
