Hello,

I would like to offer end users in a LAN, asking for this (why ? I don’t know) the capability to use a laptop (along or in replacement of hardphones) to emit and receive PSTN calls.

PSTN pass through a plain SIP trunk which does not support video (nor Opus)

How can I best integrate off-the-shelf components to implement this ?

My initial thoughts are to implement Cyber Mega Phone and asterisk on a single Linux host but I’m having a hard time to evaluate if Cyber Mega Phone is suitable for this and if enduser experience would be positive.

What do you think?
