Mac OS X 10.5.1 Breaks VOIP Again?
by Al
I’ve written previously that when Mac OS X 10.5 (aka “Leopard”) came out, it broke all of the SIP-based voice over ip applications. This was something that hadn’t been broken in the developer builds but only in the final release, thus giving people making VOIP software a pleasant surprise for “Leopard Day.”
People seem to have largely worked around the issue and released updated clients for Leopard. The Gizmo Project, which I normally use for VOIP with Mozilla, released a beta almost immediately and got a full release not long after.
Yesterday, the first update to Leopard came out, making it 10.5.1. I installed this and immediately noticed that VOIP no longer worked for software using SIP. Since I was playing around with Xmeeting as an alternative to the Gizmo Project, I figured it was just Xmeeting. That turned out not to be the case. When I fired up my work laptop, which still runs OS X 10.4, everything worked fine. As always, Skype seems to work fine but I actually don’t generally use it.
So it seems that Apple has once again managed to break the applications that use SIP with an OS update. I haven’t seen any other reports of this but I really don’t think my machine is particularly unique. We’ll see what happens.

Check out http://www.openwengo.org/ I was told it works in Leo.
Everything but the current developer version of Open Wengo 2.2 has crashed on any computer that I’ve run it on. Not a good sign of quality.
The current version has the same problems that all SIP software has on OS X 10.5.1. It fails to connect to the SIP server that works on the same network running 10.5.0 or Tiger. So, no improvement there.
Hey, what a “relieve” 2 C that I’m not the only1 who experiences those problems with SIP software on Leopard.
On Tiger (luckily I’m still running dual-boot) X-Lite runs perfectly with my voipbuster-account.
On Leopard I get an error when trying 2 log in.
Hopefully this gets fixed very soon, so i can format the drive with Tiger on it.
Greetings!
Hmmm I tried openwengo, it works even worse than X-Lite, because it tries to start (not even a window started yet) and than dies with an error:
‘The program WengoPhone stopped unexpected.’ :-(
I’ve got a dual processor 2x G4 1GHz (PPC)
with 2GB DDR memory.
Express Talk softphone from http://www.nch.com.au works fine in Mac OS X 10.5 Leopard.
@ Henning,
Just tried it…doesn’t work, because I cannot change the settings.
The settings window behaves very strange, overlapping text, i cannot comment anything and cannot enter text to fill in my data.
Maybe it works with an intel mac, but it doesnt with my PPC mac.
Preference problems anyone? Just updated to 10.5.1, but I can’t set Xmeeting up to call anyone because I can’t access my Preferences on any version – and I’ve tried every download available. Previously got my mom set up on Xmeeting, over the phone, no problems whatsoever, on her 10.4 iMac. Suggestions?
@Orwell
Its not a preference problem, but a common known problem.
There will be an update for X-Lite, but not first untill januari/februari.
Just for your information, I run 10.5.1 allready before discovering the problem.
Hey folks,
I found out that an older version of X-Lite functions on my Leopard system, namely X-Lite 2.0!
So I will not have to wait untill they update a new version.
:-)

or use SJphone from http://sjphone.org/
newest ones from http://www.sjphone.org/preview/
Brekeke Software has a SIP Server implementation that runs on OS X. I believe that it uses Java so it would be independent of any changes from Apple.
