RE: T48G using Wifi and Mulitcast paging
Most likely a setting on your Wifi AP. Most APs will filter out multicast traffic by default or apply "shaping rules" to minimize over-saturation of wireless bandwidth.

The easiest way to test if it's your Wifi or a Yealink issue is to take your laptop and put it on Wifi only. Run wireshark or TCP dump and then go to a hardwired phone and start a multicast page. You should see the multicast packets streaming in. Stop the page, wait your 135 seconds or whatever odd time value it was, and then doing the multicast page again.

If you see the RTP packets flowing in on your laptop, then wifi is fine and it's a strange Yealink thing. If you see no packets, then it's a Wifi thing.

Good old divide and conquer trouble shooting ;o)

Thanks,
-Rob
