Hello Everyone

These days lots of companies use/provide solutions for Ringless voicemail. Also I found one url stating the RVM using freeswitch.

Can we use freeswitch for it. or it is provided by the carrier/gateway to drop messages directly in the VM bypass ring.

In the above URL if we refer then 2 calls are being made to make 1 line busy and second to drop vim.

Last question: Is it being legal nowadays?

Thanks
