i am surprised why one phone has registered why other not!!! both the phones have same model both are getting the same subnet ip .... the phone which is not getting register it is giving me error " Registration Rejected:Max Pho... " i dont why some of phones are not getting register.
about CCM config i created one SRST, called tht SRST in Default Device Pool and assign Default DP to the phones ...
can any one tell me why this msg is coming on phones ...

Thanks for your reply, in start i also thought that this msg is bcoz of number of max phone registered .. but if i do "sh call-manager-fallback all" command, in it it shows me only 29 phones are registered ...
one thing i would like to mention that i have 2821 Router having SRST 4.0 and i have 7911 & 7942 phones in network, 7942 phones are not supportable in SRST 4.0 (when 7942 goes on SRST Router it only displays that "CCM Fall back Service Operating" msg on screen and rest of all screen is empty ) do you think that even the 7942 phone is not completly registered with SRST Router, Router will count it as ephone ????
