Hi Mike,
I think you said that any ICMP packets would be noticed, do you monitor
the gateway connections as well?
I've seen some devices that send out relatively small TTL values and it
can result in one way audio that is customer path specific. As mentioned
before SIP/TLS is not a true VPN

Yes, you also need the ID headers in order to pass RCD. Most customers will
(hopefully) be expecting to see this on calls someday.

2. If your network is partially TDM and partially VOIP, have you
experienced any issues with either of them? What are your future
concerns since STIR/SHAKEN does not work with TDM?
This will certainly weaken the benefits of S/S since the ID Header will
be stripped off along many paths.
is there
value in keeping the Passport information to indicate the inbound
attestation and response from the CA?
I'm wondering if I'll ever need to justify the attestation level I
present on a call, or for blocking it?
Thanks,
~Glen

SLIGHTLY OFF TOPIC:
Lately I've been getting calls to my Tmobile cell phone with CNAMs
such as Scam Likely and Nuisance Call. Even without the CNAM I
know they are call centers so don't pick up, but I'm wondering who
assigns that CNAM? I'd expect Tmobile
Hi Erick,
the only carrier who knows the number is invalid is the LEC/CLEC
that owns the block. They probably will send back a 404 Not Found
or 604 in most cases. However unless you are directly connected
to them you may not get that response returned to
urces? I don't know.

Hi Shripal,
normally calls with TF CLIDs are just billed as Indeterminant
Jurisdiction. If your rate sheets don't specify IJ calls then it
is generally the higher of the two rates.

Hi Shaun,
most systems work off CDR files (or Radius or Diameter steams) so
are proprietary in what products they support (http://oculeus.com
is one such system). There are some products that are
