Interoperability with SIP Phones
We have made every attempt to make the SipExchange server compliant
with the SIP standards so that you can use SIP-compliant SIP phones
with SipExchange. But we are finding out that not all SIP phones are
working with SipExchange because either early versions of SipExchange
has some limitations or more likely, the SIP phones do not comply to
standards
fully. So we have decided to try out SipExchange
with various SIP phones to verify their level of interoperability. The
following table describes our experience with the phones. Your comments
are very welcome. If you have tried SipExchange with other SIP
phones, please let us know your experience. |

| X-Lite for Windows and
Linux - Free |
Counterpath (formerly XTen) http://www.xten.com |
This is a very nice phone
and we have used this phone from the very beginning to test out our SIP
projects. The Windows version works very well with SipExchange but we
have not tried the Linux version yet. The latest version supports voice
calls, IM
and presence operations (buddy list) and all of these functions see to
work well with SipExchange. Counterpath offers non-free SIP soft phones that are full-featured - supports voice, video, buddy list and the works. We have not tested the server with these phones though. |
Please see this page showing the configuration screens - XTEN setup. |
| Pocket PC Softphone for
Windows Mobile |
Counterpath (formerly XTen) http://www.counterpath.com/ |
This is a very nice phone
that works on PDAs running Windows Mobile operating system. The
phone works very well with SipExchange. As with most PDA applications,
the phone supports only basic functionalities compared to the offerings
on a full-blown operating system. The phone supports voice calls only
and does not support presence operations and instant messaging. NOTE: It appears that Counterpath is not offering this software for sale any longer. It is a pity because the phone worked well. |
From the bottom-level
menu, select System Settings -> Sip Proxies. Setup the Username entry as the name of the subscriber that was created, Domain as the domain to which the subscriber was assigned. Enter the password provisioned for the subscriber. For the SIP Proxy and Outb Proxy entries, enter the name of the SipExchange server. |
| Windows Messenger for
Windows - Free |
Microsoft http://www.microsoft.com |
Windows Messenger Version
5.1 is a very promising
phone for the Windows operating system. Unfortunately, the latest
versions do not provide support for SIP servers. Therefore, we are
stuck with an older version. This makes it not a very viable phone for
the long term. The phone provides many nice features including voice and video calling, buddy lists and more but it "twists" the SIP specifications, perhaps, to work with Microsoft's Live Communications Server (LCS). We have tested with version 5.1 and voice calls and the buddy list works properly. We have been told, though not confirmed, that the later version of the Messenger is even less compliant with SIP standards. However, there are problems working with SipExchange. Namely: The phone does not work
properly when an
authentication challenge is sent by the server when the user logs out.
We have created a work-around for this "bug". See the installation
notes for details. Please make sure that the workaround has been
applied prior to trying out the presence functonality.
We do not recommend this phone for SIP communications. Instead use the
other SIP phones listed in this page.

From the top-level Tools
menu, select Options. From the Options dialog box, select the Accounts
tab. Check the "My contacts include users of a SIP communication
service" checkbox. Enter the Sign-in name as subscriber@domain where
subscriber is the user name and domain is the domain name for the
provisioned subscriber. Click on the Advanced button. Enter the
SipExchange server host name/IP address for the Server name or IP
address entry and select UDP for the Connect using entry. Here are a few screen-shots for the configuration screens - Windows Messenger setup Also, there are additional settings that you need to have on the server to fix the logout problem. Read this section for details. |
| WengoPhone for Windows,
Linux, MacOS and Pocket PC - Free and Open-Source |
Wengo http://openwengo.com/ |
Wengo is a service
provider that provides services similar to Skype. But they use standard
SIP as the communications protocol. Hence, the phone can be used with
SipExchange and other SIP servers. The Windows version of the phone works well with SipExchange including the presence and IM functionality. It has some cool features and nice user interface. But, it does behave strangely once in a while and may have a stability issue. We have not tested with the non-Windows versions yet. |
This is what we had to do
for WengPhone version 2.1.
Login/username: amit - this is the subscriber account you created from the SipConsole Password: the password for the user. SIP Domain/Realm: Enter the domain you created from SipConsole and assigned to the subscriber to. Displayname: Enter your full name. Expand the "Advanced" bullet and enter the following additional information: Server: Enter the domain name that you configured using the SipConsole. Proxy: The SipExchange server host name/IP address and the port number (5060) Check the "Force Register through Proxy" check-box. Click on "Connect" button. |
| SipCommunicator for Java -
Free and Open-Source |
Developed by the
open-source community http://www.sip-communicator.org |
The SIP Communicator team
offered an earlier version of the phone that worked relatively well
with SipExchange. Now the team is
working on a better phone and has released an alpha version but it does
not work ith SipExchange. The registration function seems to work fine
but it does not handle outgoing calls using the proxy. It is not usable
but we are hoping that we will be able to support this phone soon. |
