Android Question SIP/VOIP

[AndyW999]

A long time ago Erel said that :-

Seems like the native SIP framework doesn't support VPN:

Does it now?

I have a working SIP client but I need to connect it to a FreeSwitch server probably by OpenVPN.

Please could anybody let me know if it is possible?

Thanks

Andy.

I never used SIP in my APPs, but I deployed some asterisk and callmanagers etc, however, you only need the SIP ports (to register) and the RTP ports open usually open in the vpn. I have a lot of deployments with VPN with SIP traffic VPN and DMVPN. I did not see why the SIP framework will not work. I used a lot zoiper APP inside of VPN.
