Registrar Server :

SIP Domain Name : enter your domain or if you dont have it just put

DNS Server Address : your DNS server which your internet SP providing(ex. ATnT :

Ok so here is the new SIP configuration:

Proxy Server (primary)

Registrar Server

Outbound Proxy Server

SIP Domain name

DNS Server address

For the life of this thing and 6 hours with Cbeyond and Cisco, Cbeyond escalated this to Tier 2 support, Cisco says its the carriers fault, and it will NOT register the SIP. Cat5e connection goes from the Cisco IAD directly to the WAN port of the UC540. The NAT is defaulted, The WAN portion of the setup is correct, all the computers can get to the internet no problem....I do not know what else to do...I have until MONDAY to figure this out and I am running out of time....PLEASE HELP....below is what it spits out when I refresh the trunk status....

If any one can make heads or tails of this issue, I would be forever in your debt....

change the configuration as below

Proxy Server (primary)

Registrar Server               ----> change

Outbound Proxy Server

SIP Domain name

DNS Server address


Let me start off by saying thank you very much for your help. The SIP does register now, it is just so hard to believe that the carrier couldn't even tell me the settings. I think I just have a routing problem now, the main number rings in fine, 9545338980, but the 855 numbers when you call it say "your call cannot be completed as dialed" I am going in today to see what I can do about that, hopefully its a simple fix. I'm sure in the next few hours I will be posting my next hurdle with this system.

good to hear that :-).

what is 855 number for, need more detail(call flow etc) to help

It all FINALLY works!.....I was not told this when Cbeyond installed the circuit but the 855's are routed to local DID's....I built routes for the 855's but since they are translated into local DID's the calls had nowhere to go so I had to build routes for those and it worked...each department has its own 855 and its outbound caller ID for each department is its own local DID...the only thing I have left to do is figure out how to monitor the agents call usage, calls taken, average length of call etc. and how to setup the call accounting....again thank you Bongsu for ALL your help, I am totally frustrated with both Cbeyond and Cisco over this weekend, nothing worked and both sides blamed the other, funny to me that I get more help on these forums than I do actually contacting the TAC or the SIP carrier.....
