Well, all systems between, which decode the RTP stream on one call leg
and encode it on the other one (like session border controllers, PSTN
gateways etc.), have to support the codec of their peer on the
corresponding call leg.
If they are pure SIP proxies, they don't get involved into the codec
negotiation.
