Question about how traffic passes from phones

Hopefully this is a simple question.

How does a non-secure phone that is on a PBX connected to an asterisk over a SIP trunk communicate with a secure phone connected to the Asterisk server?

I like to think that the secure call terminates on the Asterisk and the non-secure call is somehow joined to that call on the Asterisk. Same with the voice traffic, I’m once again thinking that the Asterisk proxies the calls. Just not sure.

Thanks,

Mitch

  • I think, although I’m not positive, that if either leg of the call doesn’t
    offer SRTP, then there won’t be any SRTP in the call path.
