Paging w/ 7921 and autnonomous 1242's

Scott Fella · ‎10-21-2008

Has anyone got this to work? Currently can't get the 7921s to join the multicast stream. They do have basic data rates set and also they have QoS configured. I have 5 phones setup. 2-7961, 3-7921. Both 7961's and (2) 7921's are part of my paging-dn group. When I click the PTT button on 7921 #3 I can page the 7961's with audio, but I get no audio on the 7921's.

If you are using 5 GHz, then the default basic rates are 6,12,24 and multicast is sent at the highest basic rate from the AP. However there are some issues with mutlicast sent at 24 mbps. Recommend to make the highest basic rate 12 mbps and set 24 to optional (non-basic) vs mandatory (basic).

Ensure that IGMP snooping is enabled on the autonomous AP as well.

Recommend 12.4(3g)JA1 or later.

See the 7921G Deployment Guide for more info.
