connecting 2 IPO's via SCN

Hello All,

We currently have a customer who has a 412 and a 406V2 running 5.0.8 software. We currently have them connected together via SCN. This was our first foray into connecting 2 IPO's together so it was a little odd how we connected them. We have the WAN ports on the backs of the systems going to older Adtran Netvanta routers that connect to a PTP T1 circuit for the voice traffic. The customer has a Data PTP which supplies the IP addresses that we have assigned to each of the IPO units, this is how the IPO's see each other over the customers network which has a different subnet at each location.
The customer has had issues over the years with latency. We would go out and check the Netvanta units and talked with tech support to make sure that the units, both IPO and Netvantas were programmed properly.
We also called the network engineers that maintained the customers network to make sure that there was nothing amiss on the network side that may be affecting the traffic. They always told us that all looked ok on their end.
We have had the LEC check the T1 numerous times also and were told that all looked good.
The customer has now decided that they want to get rid of the voice PTP and send traffic either over their data network or via the internet and VPN.
Their network engineers said that they would prefer not to send the traffic over their internet connections which have firewalls that they maintain.
When I suggested that we then send the traffic over the data PTP they now inform me that the routers that they have (Adtran 604) cannot pass QoS. I now realize that this was probably my issue all along with my latency problems.
My customer received a quote for 2 Juniper J20? routers with T1 cards and an Extreme X250 switch plus programming for $18,000!!!

My question is how can I accomplish connecting the IPO's in a more economical and stable manner, as my customer is beside himself at the quoted costs.

What we want to accomplish is having the incoming calls to be routed from the main location (412) to the secondary location (406). also to have the 406 pull the dialtone across the SCN for outbound calls. I have viewed their call traffic and the most I have seen as far as active calls at one time is 7 calls.

My issue is since I do not maintain their network I am at the mercy of their company who does. Any suggestions that you folks could give would be much appreciated.
 
Please be informed that I am not a Cisco salesman but in your case, it could be more economical if you go with older Cisco gear such as 2811 router. Juniper is great router but we normally only deploy them at mega site where extreme large data / video traffic is required. It would cost you more to program the Junipers as talented techs are often hard to get.

For COS, you could order COS service with LEC such as AT&T/Verizon etc .

If you select lower bandwith codec, you should be fine as far as voice quality and you surely can fine tune it within Cisco IOS.

Multiple bids might reveal better deal IMHO.
