Bill -

Thanks for the information; I called a cisco distributor for pre-sale support before providing a bom to the customer. A few small businesses I dealt with perceived the sip as too slow for data , “they get more bandwidth at home from cable, fios etc.” The smb wanted an alternative to SIP for data rates and was willing to pay a 2^nd ISP for 30MB / $79.00 month. A Cisco distributor assured me I could use 2 ISPs with a 540, I would have to use the WAN port for the SIP trunk and as long as the data ISP gave me an Ethernet handoff I could use any ethernetport on the UC 540.

Bob,

I am not familiar with what you are saying when you say "you percieved the sip as too slow for data". The WAN interface is a 100Mb interface and is fully capable of supporting the 30Mb connection from the ISP. With that being said, the UC540 already optimizes the traffic with built-in qos features.  Unless you NEED 2 ISPs, I think you may be going overboard with the design. Your phone calls should not experience ANY quality problems, regardless of how many phones you have behind this 540. The reason for that is the afore mentioned built-in qos features. I don't know what your upload speed is, but I'm guessing it is in the 5-10Mb range. That is 5-8 times faster than a T1. You have PLENTY of bandwidth to adequately service all of the users that you have licenses for, so I'm not sure about the necessity of 2 ISPs.

I also did mention this is most likely possible in the Command Line, but it is not a supported configuration by the Small Business Support Center. I sincerely apologize for any misinformation provided to you during your call to presales. If the end-users really have to have 2 service providers, their only supported option will be to install a SA500 infront of this UC500.

Regards,

Bill

I would like to add that we are considering making the dual-WAN connectivity an option in CCA, but nothing is formally committed yet. For now, and as Bill said, you need to deploy a device in front of the UC to do this.

Thanks,

Marcos

Hi Bill -

Yes the WAN port is 100 MB but the SIP trunk is not, the SIP cost 1.5 Mb/s IP port $479 per month (1year term)  from lowest cost ISP 3.0 Mb/s IP port $958 per month (1year term) and I called 5 SIP providers.... . This is why the customer percieved the SIP trunk as too slow, layer 8, the money layer... Also most ISP's in Long Island NY are offering 30MB  business class for $79.00 per month for data. So, when you see the whole picture, this is why the customer wanted 2 ISP.

ISP 1 for the voice 8 Concurrent Conversations on SIP trunk for $479

ISP 2 30MB business class 30/30MB for data $79.00 per month

Is this over enginered? I just want to make the cut over data...

Marco or (anybody)

Do you have an example of the CLI commands on a UC-540 to get the disered results?

Data VLAN to the ISP provided cisco 800 for 30/30 mb

Voice vlan to the WAN port SIP trunk 1.5mb 8 concurrent calls.

Bill

A great guy named Joe suggested setting up a vlan x with IP address and untrust an FA port in security zone for that port, assign the vlan to the untrusted port, route the data traffic out to that vlan x. Any comments?
