400 Bad Request trying to register

[chavonbravo]

Hello, I'm using a Windows Mobile device that has Voip options, and I'm sure I have all my settings correct. This is what I have configured for Broadvoice.

user account='3212332195' password='nbpbxxxxxx'
uri='sip:3212332195@sip.broadvoice.com' allowauth='digest'
sipsrv addr='proxy.nyc.broadvoice.com:5060' protocol='UDP' role='proxy'
session party='first' type='pc2pc'
session party='first' type='pc2ph'
sipsrv addr='sip.broadvoice.com:5060' protocol='UDP' role='registrar'

Is there something wrong with that?? I'm sure it's all right, yet I get "no service" when trying to connect, and when doing a packet sniff, I see the 400 bad request error when trying to register. With similar settings others have connected to other VOIP providers, but many have had problems with Broadvoice, I've not seen one successful person write about it.
I am uploading an ethereal file with the packet captures, maybe someone can help out and see what's wrong?

As far as I can tell, it's not following RFC 3261's recommendation to construct the Contact header in your REGISTER message. Most likely it's Windows' software problem, not yours.

It's got the contact header there,
Contact Binding: <sip:192.168.2.103:12984>;methods="INVITE, INFO, OPTIONS, BYE, CANCEL, ACK"

Still can't figure this out, are there actually any broadvoice support people in here??

Best place to get a hold of a BroadVoice customer service rep would be to call one of their support lines. I am unaware of any official BV customer service reps here on the forum.
