[Freeswitch-users] Signalling from Android app

[Vladyslav Zakhozhai]

The simplest and standard way is SIP over TLS (by the way it wotks via TCP
not UDP). But it does not solve your issue.

I think that you may consider using some kind of tunneling built-in in your
App (i.e. IPSec, SSL VPN, etc).  In this case nobody knows what kind of
traffic goes through this tunnel and you have not issues with NAT in SIP
messaging. But this is non-default solution and it will not work out of the
box in FreeSWITCH, Asterisk, etc (you need point of termination this
tunnels).

But will it work properly with Asterisk or other opensource and
non-opensource or non-free PBXes? I doubt that.
