Hi Everyone,

Here is my problem.  My ISP has split the voice line (MPLS) and the data line into 2 separate connections on a T1 circuit.  The voice line has been given an internal IP address of 192.168.1.1 and is connected directly to the local lan via a switch, while the data line has a wan IP that connects to the DIR-655 router that then has an internal IP address of 192.168.1.253.  The PBX points to the voice IP as it's gateway but cannot get DNS resolution because the does not support any.   Thus the PBX is unable to get support, updates, or do any email notifications.  Inbound and outbound calls are working.

The question is, if I point the PBX to the router, what do I need to do on the DIR-655 such that I can route voip traffic in and out to the voip line IP 192.168.1.1 and allow data and DNS resolution to route through to the WAN?


Thanks in advance.

Is this a business class phone system like Ciscos VoIP phone? If so I would recommend that you probably need a business class router or specific router devices that handle these kinds of phone systems.

These home class routers are not able to support that kind of system. Yes they can handle some VoIP like Magic Jack and others, and those are home class phone systems. Sounds like your using a PBX and are trying to connect up a business class system on a home router. I don't think that will work well IMO.

Yikes. Yea, contact your IT. I would need much more info to troubleshoot that and it is way outside the scope of this forum.

Thanks guys,

I am the IT person at point for this problem.  Typically, the voip arrives on the same wan connection as the data and this is how the router was configured originally to deal with it.  The problem is that the client moved to a new location and has a new carrier that configured the WAN differently.  Seems that they split the data from the voip and configured the voip to connect directly to the lan.  The PBX is a Digium SwitchVox system.  Looks like my options are, 1 -look into a business class router that can have multiple wan ports.  2-See if carrier is willing to merge the voice and data together and send it via the same wan connection.  This shall be interesting.

I would ask the PBX Mfr if this kind of router is supported or not. Sounds like it's not. Dlink has some dual WAN routers however I don't think they are sold here in the U.S. from what I was told.

Let us know what happens.

Could you give us some specifics so we can research?

A. Current ISP
B. More info on data type. T1 yes, but HFC or Fiber?
C. Current modem or ISP endpoint.  You say the voice line is connected directly to the LAN, but from what? a VOIP modem? And you said the data line connects to the DIR-655, from what?

And honestly, this is outside the scope of what we would normally support on this forum, since these routers are intended for home use.  We will give it our best shot but you may want to be looking into alternate support. PBX vendor is a good place to start.
