Sounds like a possible loop, the "No Routes Found" recording comes off of a Sonus Networks GSX or SBC. How is the TFN arriving to your network? - Chris On 24 Feb 2014, at 9:01, Ivan Kovacevic wrote:
Hi Folks,
We are seeing something strange coming across our network. A disconnected client TFN is receiving 30,000+ calls per hour (all failing). The ANIs being used are dummy ANIs 17029983416 (no answer) and 16469820093 (recording saying "no routes found").
This is not affecting our network, although it's causing the upstream provider a bit of grief.
Not sure why someone would do this.... We are about to remove the CICs at the sms800 level, but just wondering if anyone has come across something similar?
Thanks,
