S_R2_COLLECT and R2_Q421_IDLE on several voice-ports (E1 channels)
I have a 2650XM router with a NM-HDV-E130 module. If I type the command show voice call summary, it display several channels as S_R2_COLLECT and R2_Q421_IDLE (when this happen, that voice channel doesn´t allow to make and receive calls to/from PSTN). After some time, the number of channels with this issue increases, and there is almost impossible to make or receive calls to/from the PSTN. I have to shut and no-shut the voice-port to reset the satus, but the problem comes back again.
