UCMC - Unable to sync object error, AXL code -1 received during discovery

Version seen: All Versions

Normally this is caused by bad phone data in CUCM - AXL listPhone is OK but getPhone fails, generating error as per below sample

{
"cluster": {
"id": "8df01a33c979cef84f32ed0ed1001f73",
"name": "CorningSourceInterface",
"axlVersion": "11.5"
},
"err": {
"error": "",
"reason": "Unexpected AXL Error",
"errorType": "AXL Interface",
"clientShouldBackoff": false,
"requestMethod": "getPhone",
"axlStatusCode": 500,
"axlFaultCode": "soapenv:Server",
"detail": {
"axlError": {
"axlcode": "-1",
"axlmessage": null,
"request": "getPhone"
}
}
},
"rawInputs": {
"attributes": {
"uuid": "{32B2F3DD-C406-5E36-8198-E503F0C44990}"
}
}

Solution: Perform Save in CUCM for the Phone Device in question. To find the offending phone in CUCM,

Copy uuid (highlighted in sample above) from error code in Wrangler then paste this (converted into lower case) into CUCM GUI as https://<CUCM IP Address>/ccmadmin/phoneEdit.do?key=32b2f3dd-c406-5e36-8198-e503f0c44990

this should bring up the CUCM phone device causing issue - select Save in CUCM Phone Configuration

When completed, Restart Discovery in Wrangler
