I have just about pulled out all of my hairs on this one and seeing as I don't want to be a patient of the hair club for men I thought I would post my issue here.
The design is pretty simple. UC520 using SIP for in and outbound calling (voicepulse) with a smattering of 7970s, 7960s etc... I'm able to make outbound calls with no issues, but when I try and make an inbound call I'm seeing a 404 Not Found error. Everything that I have read tells me that we are receiving the call just fine, but the UC520 doesn't know where to send it. That's confirmed with doing a debug voip dail-peers. Problem is I just don't know why there isn't a match. I want to send the call to my blast group. Hell, I would like it to ring some where even if it was just to the phone on my desk... Plz take a look and let me know where I'm sideways...
