[cisco-voip] CUCM/CUBE Sip Issue - Anonymous Calls Dropped

[Gary Parker]

I’m currently having some problems with a Cisco 2921 with CUBE dropping inbound SIP calls with

"Calling Number           : anonymous”

...with a 404 disconnect cause.

The gateway is well firewalled to only allow connections from our SIP provider so I’m happy to allow anonymous calls but I can’t figure out how to tell the CUBE software (or is it CUCM?) to do this.

CUCM is 8.6.2, the gateway is running IOS 15.1(4)M3


Below is some example "debug ccsip calls"
