Have a CME with 7921 ,7970 paging works fine to 70 from a 70 or 21 but 21 to 21 drops constantly.
The CME 4.3 and the 7921 has latest f/w.
Also wlc has f/w 4.2.130.
has anyone ran into this issue.
Phones and CME are on same subnet and same sw stack. WLC has trunk to sw stack. Multicast paging in enabled.
