Remember with CBWFQ'ing you are reserving bandwidth, but not when the Voice queue will be serviced. Voice quality does not tolerate delay or jitter.
The best would be change the bandwidth command in the Voice class map to priority. This would changing the queuing on the voice stream to PQ and change the overall queuing from CBWFQ to LLQ (PQ/CBWFQ). wrote in message news:[EMAIL PROTECTED] > Hi guys, > > Just a quick one and am sure this has been asked many times. > > Two rtrs with serial line between them.
