I think you need to explain your question in a bit more detail. What exactly are you trying to achieve?

Hi,

RTP port range is between 16384 and 32767.

extended ip access list test

permit udp any any range 16384 32767

Is this what you need?

hi Reza.. so this is literally what will i encode in the router to open the udp port?

router# config t

router config# extended ip access list test

router config# permit udp any any range 16384 32767

thanks

Hi,

Reza has explained how to create an ACL that will allow UDP packets destined to the ports in the range 16384 to 32767 (any source or destination IP). You would then need to apply this ACL in the correct direction (in or out) to the correct interface. That would allow those packets to pass through the router.

I am still not sure if that is what you are asking though - you seem to be alluding to the router communicating with your PABX system - possibly as some sort of SIP gateway or something similar. Can you clarify?

hello mfurnival,

yes.. i am integrating the pabx to the router. and this requires opening the udp and rtp port.

thanks
