Re: voip issue

The cpu of 90% on MC3810 can be because of the IOS issue. Ideally with one T1 and at max use of it, the cou should not be at 90%.

Pl. issue "sh proc cpu" and see which process is spiking the cpu on MC3810.

So ios change can fix the issue.

Now as far as 3745 goes, it does supports 2T1 and any QoS method should work fine with it.
