FTP: RETR command - BINARY transfer failed.

IP.FTP SERVER (RETR) Transfer of file '/Polycom/sip.ld' failed for remote host '10.10.20.2'.

SIZE command worked, but the file transfer failed. This means that the sip.ld file is the same as the one stored on the

phone already.

The rest of the file transfers have been removed from this debug. Confirm that all files listed earlier in this document are

downloaded.
