This is just a shot but try playing around with the SIP ALG toggle in WAN Setup.

After disabling SIP ALG in WAN setup, it works now. Thanks for your help.

    After selecting the "Disable SIP ALG" option in the WAN setting, the outgoing calls from VoIP phone works. But the incoming calls to VoIP phone only partially work, it only works right after the VoIP phone generates an outgoing call; after 5 minutes, the VoIP call is not reachable anymore. Any call to this VoIP phone will get an announcement "The subscriber you are calling is not available". Are there any other settings I need to adjust?
