In the last couple of weeks, video conferencing and calling users have been reporting a new type of nuisance spam call, some receiving up to 100 a day for each endpoint.
Spam and nuisance calls are nothing new. They have always been a danger for SIP from toll fraudsters, though until now, this has never happened with H.323 services.
The spammers use automated tools that can scan the entire Internet in minutes, searching for open H.323 ports and then placing calls to them in an effort to commit toll fraud. They behave in such a way that makes them indistinguishable from a genuine call.
Systems behind firewalls can be protected if rules are added, but many H.323 systems are simply placed on the open Internet as firewall traversal technology or services for them have typically been very expensive or difficult to manage. With no firewall to protect them, these systems are unable to identify and block the call - meaning their users will have 100s of unwanted calls with no way of protecting themselves except turning their systems off. StarLeaf users are not subject to these issues for a variety of reasons.
StarLeaf endpoints are all installed inside of their firewall - which is possible as the StarLeaf Cloud uses an exclusive firewall traversal system rather than operating outside of your firewall. Also, H.323 (and SIP calls) are directed through the StarLeaf Cloud and the all StarLeaf nodes have security measures in place that automatically blacklist calls from nuisance IPs.
This means StarLeaf users are fully protected from receiving this new type of spam call - in the same way they have all been protected from receiving nuisance SIP calls in the past.
If you are not a StarLeaf customer, the bad news is that there is not yet a solution other than manually blocking individual IP addresses or unplugging your system. The good news is that we are still running our
Trade-in offer, so if you want to switch to a service that is simple and secure, there really is no better time.
