[VoiceOps] Misconfigured e.164 addresses in From: field

[Zilk, David]

How common is it that SIP received from a carrier would have a misconfigured e.164 address in the From: field?

We are seeing calls from various US numbers appearing with a leading '+', but no '1' country code.  Therefore they appear to be originating from a foreign caller.  An example would be:

From: sip:+208488xxxx at aaa.bb.cc.dd:5060;user=phone

Which would appear to be from Egypt (country code: 20) but is really from Boise, Idaho (NPA: 208)

We are seeing this from at least one of our carriers. Do we need to just live with this, or should it be something that we try to get fixed? It doesn't impact routing of calls, but it messes up our statistics.
