The call is using G729 and doesn't use MTP/Transcoder. Default gateway's set properly.
The strange thing is after 'hold' and 'resume' softkey only on HQ phone, the call is fine with two way voice. I checked the CME router interface if the voice packet is coming in from HQ and the interface counter was increasing and showed 31 or 32 Kbps steady for 5 min incoming packets. But the CME IP Phone showed 0 for Rx.

Is the call going through an MTP/Transcoder? I would check your DHCP scope for the HQ phones- is the default gateway set correctly? If the call passes through an MTP/Xcoder- is the default gw there set correctly? -- Vik Malhi - CCIE #13890 Senior Technical Instructor - IPexpert, Inc.

The call between HQ and CME using GK is established but found that only HQ phone can hear the voice. CME phone cannot hear the voice. But, I can hear voice on CME phone only after I press "Hold" and "Resume" softkey on HQ phone. I rebooted the CCM server but didn't fix it. Why this happen? James.
