Interoperability with SIP Phones
We have made every attempt to make our projects compliant
with the SIP standards so that you can use SIP-compliant SIP phones
with SipExchange and Jiplet Container. But we are finding out that not
all SIP phones are
working because either early versions of our projects had some
limitations or more likely, the SIP phones do not comply to
standards
fully. So we have decided to try out SipExchange and Jiplet Container
(with the Jiplet Reference Application installed)
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 or Jiplet
Container with other SIP
phones, please let us know your experience. |

| X-Lite for Windows and
Linux - Free |
Counterpath (formerly XTen) http://www.counterpath.com/x-lite.html |
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 and the
Jiplet Container running the Jiplet Reference Application, but we
have not tried the Linux version yet. The phone supports voice
calls, IM
and presence operations (buddy list) and all of these functions seem to
work well with our projects. 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. Note on presence behavior: When the X-Lite user logs in and a contact in the buddy list is off-line, the phone starts a subscription but it is immediately dropped because the SUBSCRIBE response has no Contact Header (the contact is offline). When the contact later comes online, the X-Lite phone does not pick up the status change immediately due to the dropped subscription. However, after some time, the X-Lite phone re-subscribes and then shows the contact's online status. |

| Pocket PC Softphone for
Windows Mobile - Commercial |
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, Password and Domain as described in Note 2 above. For the SIP Proxy and Outb Proxy entries, enter the SIP server address information (see Note 1 above). |
| PhonerLite for Windows - Free |
PhonerLite http://www.phonerlite.de/index_en.htm |
This phone works well with
our projects. The voice and the IM work well. The phone does not
provide video capability yet. Unfortunately, the presence functionality
offered by this phone is not supported by SipExchange yet. |
From the top-level menu,
select Options->Configuration. On the Server sub-tab, enter the SIP server address information (see Note 1 above). Also, checkmark the 'Register' box. For the Domain/Realm, enter the domain name described in Note 2 above. On the User sub-tab, enter the User name and Authentication name (typically the same) and Password as described in Note 2 abvoe. |
| iSip for iPhone/iPod -
Commercial |
VNET-CORP http://vnet-corp.com/iSip.htm |
This phone has promise. We
have tried it out on iPod with the server running on Windows. So far we have been successful in registering the iSip phone and having it receive a call from another registered user. We did have to turn off the windows firewall completely. Just having a firewall exception for udp/5060 wasn't enough, the iSip couldn't register until the firewall was off. We have not yet been able to complete a call to another registered user from iSip. This needs investigation. |

| Windows Messenger for
Windows - Free with Windows |
Microsoft Corp. |
We test with Version
5.1.0680, pre-Microsoft Office Live Communications Server.
Later versions do not work as they are less compliant to SIP RFC
standards. We were not able to make the messenger send or receive instant messages. However, you should be able to establish voice and video calls. We have not been able to make messenger work when TCP/IP is selected as the transport protocol. The messenger cannot handle an auth challenge when the user signs out. It keeps re-sending the un-REGISTER message and we keep challenging. We are not sure if it is a bug in the messenger or design intent. As a work-around, in the server.xml file, modify the <realms> element and modify the attribute "auth-on-logout" to be "false". Please read the comments on this in that file with regards to the security implications. If you want to check out the presence/buddylist operation, you must set the "auth-on-logout" (see above) to false; otherwise your other users won't be able to see the online/offline status change of the messenger user. But even with this setting, when you logout with messenger it will continue sending unregister messages for some period of time even after the messenger login page pops back up. If you log back in with messenger too soon, your other users will show the messenger user as offline even though you have logged back in. The reason for this is because after the re-login REGISTER message has been processed by the server (and the online status sent to watchers), if an un-REGISTER message from the previous logout is received at the server, the server will notify the watcher(s) that the messenger user has gone offline. As a work-around, be sure to wait enough time after logout (40-50 seconds) before logging back in with messenger, otherwise your other users may not have the correct status information for the messenger user. |
