OfficeRoute SIP security options
Sadly, there are bad folks out in the world who try to take advantage of unprotected VoIP gateways to make free phone calls.
The default policy of Freedom Fone is to only allow authenticated SIP calls. However, in order to allow unauthorized users to call into Freedom Fone via SIP (which is free of charge and only requires an Internet connection), we have implemented a solution to facilitate this.
Furthermore, to block VoIP scanners and other unsolicited traffic hitting the platform, we have implemented a firewall that blocks unwanted traffic. For more information on setting up your firewall and whitelist see the Sharicus_2S7_developer_guide.
