Has anyone been able to get a CME to register with Flowroute successfully? I have done with another router with the credentials/authentication configuration under SIP-UA with no problem, but this other router won't register. Flowroute came back with this message. Anyone have any ideas? Let me know if you need to see any config.
I'm not familiar with the CUCME; however, I did notice your REGISTER packets contained interesting signaling. Currently your system is sending the following REGISTER packet:
U 2012/11/24 21:31:26.823441 72.201.112.131:51910 -> 216.115.69.144:5060

You'll notice the register requests comes from your IP 72.201.112.131 and port 51910; whereas your Contact filed specifies the same IP, but a different port of 1557. I believe there is some SIP ALG or SIP aware setting on a router or on the Call Manager which is re-writing/mangling your SIP packets. Because of this, when Flowroute replies to your register request with a request for authentication, your CUCME does not reply with a REGISTER packet with authorization information.
