maemo.org - Talk - SIP problem on N800 with OS2008

On the topic of SIP problems on N800 with OS2008, I signed up with Gizmo project, and I've successfully made outbound gizmo calls, but I haven't ever received one - just a lot of missed-call notifications.

Just to see if it changed anything for me, I tried using RTCOMM's internet phone support to try to make/receive SIP calls, and no dice. In fact, it seems to cause the gizmo client on my brother's 770 and his desktop to crash when I call using RTCOMM.

I'm most interested in getting RTCOMM working, because then I don't have to have Gizmo running all the time in order to receive calls.

Here's my account setup information:

Quote:

[Wizard]
User name: (my gizmo login username) @ proxy01.sipphone.com
Password: (duh)
Use for PSTN calls: [ ]

Account Name: Sipphone

[Advanced - Connection]
Transport: Auto
Outgoing proxy: ___________ (blank)
Discover public address: [+]
Keep-alive mechanism: Auto
Keep-alive frequency: 0

[Advanced - Authentication]
Authentication user name: _____________ (blank)
Password: _____________ (also blank)
(how is this username/password different from the ones I gave in the wizard?)

[Advanced - STUN]
Auto-detect STUN: [+]
STUN server: __________ (grayed out)
STUN port: [3478] (grayed out)

After adding SIP account information to one of my pre-existing contacts, it now shows two sip accounts that I can call:
gizmo_username@proxy01.sipphone.com [SIP] _______ (blank)
gizmo_username@proxy01.sipphone.com [SIP] Sipphone

Why are there two, and are the both the same? Does it matter which one I use? Any suggestions as to why this isn't working?
