Bypass Feature Codes During Call


We have an issue relating to the feature codes during calls. One of the insurance companies we deal with requires us to enter insurance ID’s with letters by pressing *, followed by the key for the letter.

The problem is that asterisk is processing the * as a feature key. So entering *2 for letter A is initiating a transfer in call.

Is there any way to create a feature code to temporarily disable responding to feature codes? So if a user presses *332 before a call, feature codes are disabled until the end of the call?

Thanks for your help.

Does anyone have any idea how to accomplish this? Thanks again.
