I have a VVX500 5.7.0.11768 that is displaying the wrong CID name on incoming calls. The caller "Britney" was previously named "ESF" on the Metaswitch and VVX500's line key speed dials. After the name was changed TO Britney, it still shows "ESF" on all phones receiving calls from Britney. I don't see any references in the Metaswitch to "ESF" anywhere.
We are allowing local contact storage (no directory coming from provisioning server). Customer checked and that number is not stored as a local speed dial key or directory entry on his phone with the wrong name. Multiple other phones are also seeing the wrong name but in the SIP signaling to the phone I see Britney being sent. I've narrowed this down to something in the phone(s) but I don't quite know where to go from here. I don't want to factory reset 50+ phones. I'm 1000 miles away so can't go there in person.
Is there a way for me to download the phones "local contacts" to see if there's something I'm missing OR that the customer missed?
Any suggestions? Specific logging in the phone I should turn on besides SIP?
