I'm not sure whether this is the case with you, but it is a common
misconception that traceroute uses 'ping', or more correctly ICMP. It
does not - it uses UDP, and you can set the UDP port to use to match
that of your application (IAX, SIP) so that routers are likely to react
exactly the same as with 'real' data.

(Having said that, there are enough problems left with traceroute, like
routes that aren't the same in both directions, etcetera).
