Prevent IPM Malicious Call outbound calling

Does any one know how to prevent outside callers from making unwanted calls to international numbers from IPM? We have done all the normal telephony CoS settings and account codes. Some background on our system, calls are answered by AA menu, users are using the FMFM feature, we need to make International calls during the day and night. But we we look at CDR there are calls being made from IPM to international numbers. I cannot tell how to stop this, any help would be great. We are using IPM 7.1 with NBX.

Re: Prevent IPM Malicious Call outbound calling



This issue has been documented in the HP Knowledgebase, although the document is written with a traditional VCX IP Telephony and IP Messaging setup in mind, not IP Messaging with NBX.


I suggest the following:


-Change the password for the AA mailboxes to something long and hard to guess, as the Virtual Calling Card settings on those mailboxes are used to transfer calls and are vulnerable. Do the same for anyone using FMFM. Remind users to change their mailbox passwords on a regular basis and to always use complex mailbox passwords.

-Disable FMFM for anyone that doesn't explicitly need that feature, as that is how most malicious outbound calling is done. -Limit the amount of minutes in the Virtual Calling Card on mailboxes using FMFM to the absolute minimum required.
