Google Chat QoS settings

Question

Has anyone figured out what the correct ports are for QoS settings for Google Chat voice converstations? I need to boost the priority of these packets on my home network, but I can't find any docs on what to set.

I'm hoping that someone out their has either found it or figured it.

Thanks

From How do I allow my internal XMPP client or server to connect to the Talk service?:

To allow full voice and video interoperability with the Google Talk service, you must:

• Allow your XMPP clients to connect to all IP addresses contained in the IP blocks listed in Google's ASN of 15169, on:

  • UDP ports 4893, 19295, and 19302
    or
  • TCP port 19294

The voice traffic goes over port 19295. So i created a high priority rule for:

• Protocol: UDP
• Direction: out

• Destination Port: 19295

• Protocol: UDP

• Direction: in
• Source Port: 19295

Or just use Process Monitor, filter it by

• Process Name: googlevoicechat.exe
• Activity: Network

and watch the screenfuls of UDP voice traffic:
