Until two days ago, I had an IVR set up and working well on my Elastix system. Sometime during the night of 5/12 it broke. I did not make any changes to Elastix at all, NONE! I have time conditions set up so that calls can be routed to extensions or voicemail based on time of day. As of right now, If during normal working hours, I route inbound calls to an IVR, my provider Callcentric gets "SIP/2.0 404 Not Found." If I route calls to an extension, they are completed successfully. I have deleted the IVR and rebuilt it with a different name with no success. Also, if instead of an extension, I route calls to the Phonebook, calls break. Tried an IVR without the phonebook option, still broke. Any ideas?
