I've just switched to UFB and my ISP has given me a router which seems to have a design fault preventing my SIP phones from working.  It has a SIP client built in and although it is disabled, something is causing communication issues with my SIP phone and SIP provider, so I want to purchase my own router to replace it.

The current router has IPoE selected and a 802.1P Priority and 802.1Q VLAN ID.  I'm not sure if all VLAN capable routers support these settings or not.

I'm looking at purchasing the MikroTik RouterBOARD RB751G-2HnD Gigabit Wireless Router.

Will this work?

Thanks.
