FreePBX IVR slow to respond

If you’re using FreePBX or one of the distributions that use it such as Trixbox, Elastix, PBX-in-a-Flash and are having a problem with IVRs being slow to respond it it is worth checking that you do not have “Enable Direct Dial” enabled for the IVR.

This option allows a customer to dial an extension number rather than an IVR menu option but this means that FreePBX has to wait to see if an extension number is being dialled, which can introduce a delay.

If you don’t need callers to be able to dial extensions from an IVR then you can turn this option off.
