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.
