-Signaling can be forced to go through the proxy, but not the media.
If you want non-end-to-end media, use a media proxy.
-Have a look at SIP trapezoid [1] [2] and decide what you want to go
through the proxy (via, R, RR) and what end-to-end
-Check your UAs' (i.e. phone) outbound proxy configuration.
