My Cisco 2821 router have 2 PVDM2-64. The "sh call active voice echo-cancel summ" result are A/F :
Voice-GW#sh call active voice echo-can summ
CallID Port DSP/Ch Codec Ecan-type Tail Called # Dial-peers
0x111BDFE 0/1/0:15.30 0/1:5 g711ulaw SW-Extend 64 ms *29277728 797/22
0x111BEB2 0/1/1:15.31 0/1:1 g711ulaw SW-Extend 64 ms *082311888 797/40
0x111BEB4 0/1/0:15.31 0/1:2 g711ulaw SW-Extend 24 ms *62379 797/26
We find that the call at port 0/1/0:15.31 have echo problem. We monitor several times and find the echo occured when the DSP/Ch is 0/1:2 or 0/2:2. Please help to mention me the DSP/Ch 0/1:2 or 0/2:2 is which PVDM2-64? Does it mean one of my PVDM2-64 failed? If yes, which one of PVDM2 failed?
