Reomte extension using mobile network

I want to use a sip cilent on my mobile phone as an extension while away for our main landline. Are there any best practices for this? think of a vpn from mobile to freepbx server.

Ia there any security issues / dos and donts

thanks

Been using the OpenVpN Server configured with System Admin Pro and Android OpenVPN client with success:

A general recommendation for VOIPing from cell phones is to use TCP rather than UDP to conserve battery life. That would go for either direct connections or VPN’s.

Thanks both for you advice.

Will have a play around, any security issues i should consider?

Generally your server should have the security applied. Attacks against voip clients on a cell phone would be a new thing. I am not saying it can’t happen but we would have to wait until such a vector be identified.
