Product Name: CISCO 7960
Product URL: http://www.cisco.com/warp/public/cc/pd/tlhw/prodlit/7960_ds.htm
Vendor: CISCO Systems
Supported Protocols: H.323, SIP
Platform: N/A
Description:

Operational Experience: It supports H.323 under the assumption of having a Call Manager, which is a CISCO software product to manage CISCO hardphones. The communication between Call Manager and CISCO 7960 is done using the CISCO proprietary Skinny protocol (not a standard H.323 protocol!), therefore the standard H.323 communication with an external client is only performed with the Call Manager and not with the phone itself (limited standard compliance of the phone). It supports also SIP protocol but from a standard point of view. With the following firmware (Application LoadID: P0S30203; BootLoadID: PC03A300) it was found to be perfectly interoperable with VOCAL system and with MSN messenger. Please pay attention that Power Cord is not included in default selling configuration. Take care of buying it or delays will occur before you can effectively use it (because of CISCO vendors slowness). Overall Evaluation: Good hardphone. A little bit too expensive and not completely H.323 compliant. The SIP part is very good and standard compliant.

The phone has excellent desing. It is very comfort to use, even during long conversations. The display is big enough to be seen even from a greater distance. The phone has 6 lines. A SIP image has to be loaded into the phone before it can be used as a SIP phone. SIP standard compliance is very good, up to 6 SIP accounts can be registered simultaneously.

Unfortunately it is not possible to decline an incoming call, the phone can be switched into Do-not-disturb mode, though. Short packets containing just four zeroes (often used to keep the NAT bindings alive) freeze the phone. This should be hopefully fixed in the latest SIP image (not tested yet).

Product Name: Adtech SI-150 IP Phone
Product URL: http://www.adtech.be/text/si150.php
Vendor: Adtech
Supported Protocols: H.323, SIP
Platform: N/A
Description:

Operational Experience: It supports H.323 but with a certain version of the firmware we have experienced some interoperability problems with standard H.323 clients (NetMeeting). As regards as the SIP part, with the firmware version SIP 2.07.06 CS 49AC, it showed some interoperability problems with VOCAL systems and MSN messenger. Some bug fixes are needed in order to avoid hook and crash problems of called clients. Overall Evaluation: Not yet mature hardphone (at least with the firmware version we tested). Quite cheap.

Product Name: Komodo Fone (now Cisco ATA)
Product URL: http://www.cisco.com/warp/public/cc/pd/as/180/186/index.shtml
Vendor: Cisco (formerly Komodo)
Supported Protocols: SIP, H.323
Platform: N/A
Description:

Black-phone-2-Ethernet/analog-line adapter, both H.323 and SIP currently SIP only for the adapter. The adapter supports two lines, only one of them at a time can use G.729 codec, the other one can use G.711 only. Supports symmetric signalling and media and can work from behind NATs. Standard compliance is good.

One of the nice features is the possibility to create dialing plans using regular expressions. Any analog phone that supports DTMF dialling can be connected to the adapter.

Product Name: BudgetTone-100
Product URL: http://www.grandstream.com
Vendor: Grandstream
Supported Protocols: SIP
Platform: N/A
Description:

This is the cheapest SIP phone available at the time of completing this document. The price is very low, but you get what you paid for. The phone is mostly standard compliant, from time to time there are some interoperability problems but the manufacturer fixes them quickly. The biggest problem of the phone seems to be its HW. The phone can dial numbers only, it supports STUN and symmetric media and signalling. Many codecs are supported. iLBC support has been announced. If you need the cheapest phone available then BudgetTone is your choice. Be prepared to receive a phone that looks like a toy with not very friendly user interface.

Product Name: optiPoint 300 advanced
Product URL:
Vendor: Siemens
Supported Protocols: H.323
Platform: N/A
Description:

The former HiNet LP 5100™ (in 1999) comes without an integrated switch and supports only 10 MBit/s. The supported codecs include G.711 and G.723. While in theory multiple firmwares can be used on this phone, the most popular was the H.323 (V2) firmware.

Depending on the firmware/application version the phone can be remotely configured via HTTP (using port 80 or 8080 - depending on firmware) and (sometimes only) using a special Windows Deployment Tool that allows configuring multiple ones at once.
To upload a new firmware, older versions required using DHCP and TFTP to update the firmware and FTP to access the application file.

New firmware versions have been seen booting the phones once in a while - regularly, when the phones aren't registered to a gatekeeper and without obvious reason while registered.

The telephones support the H.323 feature of Registration KeepAlive, but ignore the registration timeouts from the gatekeeper and resend their registrations every 60 seconds. If they are not currently registered the interval decreases to 30 seconds.
The telephone does not support the FastStart protocol feature (at least not in the old versions).

Product Name: IP Phone 7905
Product URL:
Vendor: Cisco
Supported Protocols: H.323
Platform: N/A
Description:

Very simple H.323 phone without H.450 support or integrated switch. Exists in two version: Either with AC adapter or only with Power-over-LAN support.

This is a cheap brother of popular 7960. The phone has smaller display but the design is as comfortable as in 7960. The SIP image is quite simple but standard compliant. The phone allows to register just one line, it can dial numbers only and it is not possible to dial a domain (@iptel.org for example). It can be configured through a web interface but the web interface is very basic and has some shortcomings.

If you are looking for a cheap but well designed phone and do not mind that you will be not able to dial SIP URIs, 7905 is a good choice. By default it is not shipped with power supply (Cisco assumes power over ethernet) so do not forget to order one.

Vendor: innovaphone
Supported Protocols: H.323
Platform: N/A
Description:

Excellent, full-featured (H.450, ...) H.323 phone with a fair sized display. Comes with a alpha-numerical keyboard and eases entering URL addresses. Can access phone-books via LDAP (not tested). Supports overlap dialing.

Early protocol firmwares had a problem when an incoming call has been cancelled by the caller (receiving a RELEASE COMPLETE while still ringing) when the phone continued ringing and showing a TRAP/error dump on the display when going off-hook. (This problem might be long fixed).

Early hardware had a problem of an incorrectly applied capacitor leading to a fading display (contrast). Contact Innovaphone for a replacement.

Product Name: i2eye DVD-1000
Product URL: http://www.d-link.com/products/?pid=8
Vendor: D-Link
Supported Protocols: H.323
Platform: N/A
Description:

A broadband videophone hardware with built-in camera. Video and audio signal can be accessed via cinch connectors to connect television hardware. An external microphone can be connected.

The DVC-1000™ has a very minimal H.323 support. H.323 is used to setup a call, while address resolution is done using D-Links LDAP server. The address of the LDAP server is fixed and can not be configured. The D-Link LDAP server can be used for free for all DVC users but doesn't offer resolving other addresses.

To make really use of the DVC hardware one needs a proxy instance for dialling that calls the target and the DVC (set to auto reply) at the same time and passing messages through.

Platform: Windows
Description:

The VCON Escort hardware H.323 and H.320 client is a PCI-based card that can be installed on any standard PC running a Windows OS. It allows connections at up to 1.5Mbps and includes features for data collaboration (T.120), quality of service (QoS) and interactive multi-cast for allowing viewers to watch a conference over a multi-cast network. It generally performs well, but compatibility with PC video cards seems to be crucial for trouble-free operation, as in some set-ups, sudden crashes during long operation are not uncommon.

Product Name: VCON Falcon
Product URL: http://www.vcon.com/solutions/videoconferencing/group/Falcon/index.shtml
Vendor: VCON
Supported Protocols: H.323
Platform: N/A
Description:

The VCON Falcon is a set-top-box H.323 and H.320 client. It includes a quality camera and microphone. It has a wide array of audio and video connectors to allow it to inter-operate with projectors, screens, multiple video and audio sources, as most often found in a group-videoconferencing settings. It is a reliable device, but the remote controlled management interface is difficult to work with and a bit limited (e.g. H.323 aliases can not include special chars at all).
