Hi guys, we currently run an RB1000 in our core network, we have about 50 DSL tails terminating on an LNS which then go into a VRF separate to our router. This then feeds into our router and on the other side we have some servers and an Elastix PBX which we use to provide trunks to customers for their PBX's.
We are having serious problems with voice quality which we just can't seem to track down.
For customer using a trunk we supply a dedicated DSL circuit, so we don't have data issues on that side, the problem is that the customers get choppy voice most of the time, sometimes it's fine, but mostly it's not.
The router is only just ticking over at around 3-6Mb/s and our carrier swears that their network is all good.
Everybody is telling me to ditch the Mikrotik and put cisco in, I have used MT's for years and like them, but I am concerned that perhaps this RB1000 is not handling the SIP traffic properly.
I have disabled all rules, mangling, queues, etc, it's really not doing much at all and this is getting very frustrating.
I am going to get a cisco configured up today and put in there tonight to replace the mikrotik, but I am keen to hear from anybody who has had any voice quality issues with traffic going through a routerboard and what they could do to rectify it if anything as this is a seriously bad problem for us now as we are just about to start losing our customers
Thanks for your help
