Pinchas, I never looked into intl. CLI but I believe it's only mandated for CLI that originates with US CLI. I just did some test calls where the CLI was from Cyprus using non US carriers (BICS, Bezeq, Cyta) and N2P (US based) and in all cases except one the calls were sent unsigned. In one case it was signed with attestation B. On Wed, Sep 20, 2023 at 11:16?AM Pinchas Neiman via VoiceOps < voiceops at voiceops.org> wrote:

Hi, A friend of mine complained to me about receiving numerous robocalls from international sources. While it seems to be way above average, and he seems to be targeted (due to popularity, age, etc.), the point is that international robocalls are still continuing.

I am wondering about the efforts by the US government to mitigate robocalls, and whether all the implemented traceback methods are relevant only for US-originated calls, or whether they will work also for international calls. Basically, I wonder whether it?s possible to trace back an international call, and how much this trace back will help. (Could they originate a call without assistance from a US-based company?)

I offered him a simple solution to place an IVR on incoming calls, so at least he could filter out the robots. Maybe there are other practical solutions.

Any thoughts? -- *Pinchas S. Neiman* Software Engineer At ESEQ Technology Corp. 845.213.1229 #2

I know a lot of international carriers are trying to get their own STIR-SHAKEN certificates because they don't want their traffic to be blocked. MARY LOU CAREY BackUP Telecom Consulting Office: 615-791-9969 Cell: 615-796-1111 On 2023-09-20 10:15 AM, Pinchas Neiman via VoiceOps wrote:
