Asterisk Security (Large Number of Congestion Entries in CDR Report)

Find more Network And System Administration remote jobs posted recently Worldwide

Im looking for someone who is an Asterisk and Security expert to consult me regarding securing a VoIP server. I have an Asterisk FreePBX installation that has 4 remote extensions. If you review the CDR Report, you will see thousands of daily entries that are listed as Congestion with CallerID from random, non-existent extensions. The destination always shows s [from-sip-external]. I just need someone who can help me understand what is happening and how we can minimize these entries. Thank you in advance.
