I've been playing with verto and found quite easy to set up a simple client. I can do verto/verto calls and verto/SIP calls.

In the verto/verto scenario I'm using bypass_media set to true, just for the sake of minimizing resource usage on the FS host.

My favourite feature is verto.attach: during a call I can refresh the tab and after the client re-logins FS offers the SDP for the current session, resuming the call. This is working in my testing environment, but only for bridged calls.

When bypass_media is true, in verto/verto calls, when user A refreshes the tab, client A creates a new verto instance and uses a new set of ports for RTP, while client B keeps trying to send STUN requests to the previous set.

Client A never transits from "Stream Success" into "ICE Complete" (from recovering to active), and the call is not resumed.

Assuming I don't want to bridge media in verto/verto calls, would it make sense, after FS sends the verto.attach method to client A, for FS also to send a "session refresh" to client B, with client A's SDP?

Thanks,

Giacomo
