I couldn't get it to connect to any of my SIP accounts, whether in my LAN or on the internet, although every other SIP client I have works for the same accounts.

When I tried to dial, i heard the ringing tone but since the client didn't connect, nothing happened so I hung up... but the ringing tone kept on going and going.

Then I tried to quit the app and it took half a minute.

Then I started it again, and I got a lovely SPOD for about 5 minutes.

I found this in console.log:

ExpressTalk(21384,0x1824e00) malloc: *** vm_allocate(size=1069056) failed (error code=3)
ExpressTalk(21384,0x1824e00) malloc: *** error: can't allocate region
ExpressTalk(21384,0x1824e00) malloc: *** set a breakpoint in szone_error to debug

repeated a few times. I couldn't find an application log.

Running 10.4.11 on an iMac.
