2800 IOS Bug

Unanswered Question
Nov 7th, 2007

When upgrading to an IOS that supports SRST 4.0, I have found that now there is a digit delay when using an outside vendors' IVR.

Using IOS c2800nm-adventerprisek9-mz.124-9.T1.bin or c2800nm-spservicesk9-mz.124-11.XW3.bin there is a noticeable delay.

If I downgrade back to the IOS c2800nm-spservicesk9-mz.123-11.T10.bin then I don't get the delayed response.

Has anyone discovered a work around?

SRST 4.0 is needed because it recognizes the 7941 and 7961 phones.

Solution: Problem was incompatibility with DSP 5.0 (which was a solution for echo problem) Need to delete DSP 5.0 and then reload router for new DSP firmware to update - Which in our case was 8.4.6.
