Simple priority Setup Help

Hi,

I am new to the Routerboard OS and am slowly finding my feet using the wiki and other articles etc.

I need to setup priority on my router so that all VOIP/SIP traffic going to and from a specific IP (SIP server) is allowed through no matter what else is happening on the line and if necessary all other traffic is slowed down to allow the SIP traffic through unimpeded.

I have tried creating a queue tree packets marked in the mangler, gettting a priority of 2, but though it works if the call is initiated before the line fills, if we mas out the bandiwdth the SIP is slowed down and or dropped.


So I need everytin going to and from a.b.c.d to be marked as SIP and everything else marked as other or somthing, and then the SIP to be given maximum priority and the rest lowest priprity.

anyone got any suggestions

Thanks in advance
