I've got a UC540 that I've been using for lab purposes. I've been using a test trunk from our sip provider. I'm finally ready to make the switch to our live trunk. Has anybody tried to switch the SIP trunk configuration on a running config before? I've called tac, they're clueless. I had a capture of a running config of the test trunk in operation, Only a few parameters needed to be changed to switch to our live trunk. I took a capture of the running config after changing the trunk and there were some major changes that I believe are what is causing my internal server 500 error. I'm under the impression that this has to be done via CLI, because I've made several efforts to get it to happen with CCA. I did take my box down to a default config and try it. Though it didn't take the first time I applied it, I loaded up the config where I saved it with no SIP configured, I went in to configure it and sure enough the parameters were there and it was running. This told me that saved configs don't carry the SIP configuration over. What is in the CCA configuration is what carries over I'm assuming. However my problem is that I have a configuration that I want to move over not completely redo just because I want to change my SIP info. I do have ACD and multiple auto attendents configured. I'm stumpped and so is tac apparently because they're not getting back to me.
I've tried pulling down the trunk to none and then configuring it. Still no go. Also tried that and then install the old config again..same results. I'm able to make outbound calls no problem. Inbound calls are where my trouble is. I can see the traffic reach my box, but still internal server error!
