I have an ECS with a 4VML (with the flash upgrade). Recently, calls coming in from the customer's 888 number (forwarded from a third party [Ring Central, if it matters]to thier main number) are not processed correctly in the VML. Calls directly to their main number process fine. If I call the 888 number, I get varying responses from the AA menu. (ringing a wrong extensions, sending me to the directory, sending me to an invalid MB, etc). If I call their local main number, everything processes just fine.

I have tinkered with the VM settings in Class 4, and also the config settings in the VML. Same results no matter what I do. This system had been working fine for years. Of course, Ring Central says they didn't change anything. Any ideas?
