4569 is IAX2, 5036 is IAX, 5060 is SIP Signaling.  Remember these are
all UDP.  Looks at the logs from your Cisco, they will tell you exactly
which packets are being blocked.  Assuming you put deny "ip any any log"
at the end of your access list (having the router log to a syslog server
somewhere is also helpful.
