SIPY-510 — SIP YP map format is older than proxy version
The SIP proxy has found an existing YP (registration) map file with version not corresponding to the one needed by the current version of the proxy.
The proxy cannot start.
You have to remove SIP YP map file (for its name, see sip-proxy configuration file, or the Kernun CML configuration) and start proxy anew. The file will be recreated in a few minutes.
