Help: Cannot receive Google Voice in bound call

I have dockstar+Asterisk 1.8.7.1+GV installed. From one day, I just seem lost my ability to get any incoming calls.
The same set of gtalk.conf, sip.conf, extension.conf, and jabber.conf works just fine for another Google Voice account. (yes, I have two! Who doesn’t :p)

The only difference I can see is when do "jabber test " for the one not working, I got
User: a1@gmail.com <<<a1 is the
Resource: Talk48E35BA3 << should this be asteriskxxxx?
client: asterisk.org/xmpp/client/caps
version: asterisk-xmpp
Jingle Capable: 1
Priority: 30
Status: 1
Message: Online and Available <<< this is not the status I set in jabber.conf

I made sure that I have signed out Gtalk from every other device I can think of.

For the one that works, I see
debian*CLI> jabber test
User: @gmail.com
Resource: asterisk1421C6EC
client: asterisk.org/xmpp/client/caps
version: asterisk-xmpp
Jingle Capable: 1

Status: 4
Message: I am asterisk [ And you can too! goo.gl/0DD1I ] <<< correct message

Can anybody help me to debug further?

Thanks!
