VoIP Security

From AAISP Support Site

Here are some features that A&A provide that will help prevent fraudulent activity on your VoIP service.

SIP Password

  • A number will have a sip password, this can be changed from the control pages

Call Rate Limits

  • National outgoing calls can have a price limit (default = 20p/min)
  • International outgoing calls can have a price limit (default = 2p/min)
  • International calls can be disabled (setting price limit to 'Free')
  • National calls can be disabled (setting price limit to 'Free')

Contact AAISP if you're needing these limits changed.

IP access

  • IP Lockdown - a VoIP number can be given an IP address to which is only allowed to register (ie you can add the IP of your phone, and only that phone will be able to register)


Other Tips

  • Secure your VoIP phone, eg have HTTP passwords or PINs, or/and firewall to prevent outside access
  • If you run your own PBX, ensure passwords are secure
