I have implemented a 2821 VG with 2 E1's PRI, i have a problem with some channels in one of the E1's.
these channels drop the call immediately with Disconnect Cause no resource (47).
I make some debugs and the error when the call is disconnected is
Aug 26 23:59:01.014: ISDN Se1/1:15 EVENTd: process_pri_simple: msg 118, call id 0x804C, bchan 28, call type VOICE

for the failed call is attached.
The IOS image is C2800NM-ADVIPSERVICESK9-M), Version 12.4(24)T
can you please help me on this. why these channels dropping the call?
You may be hitting this bug:
What happens is if you have an allocation failure, any future calls over that channel also fail with the same error code.
Check the bottom line of 'show voice dsp group all' to see if you've had any allocation failures.
