[OpenSIPS-Users] How to route to voicemail on destination busy?

[Gary Nyquist]

Hi,

OpenSIPS routes a call to a SIP device (destination).
And (say) the device returns "486 BUSY" to OpenSIPS.
Now the call needs to be routed to the Voice-Mail server (another SIP device).

How to do it in opensips.cfg?
Any ideas?

Thanks.
Best Regards,
