Re: [SR-Users] STIR/SHAKEN, is a number format mandatory?

According to ATIS-1000074-E “ the term "valid telephone number" refers to a telephone number that is a nationally specific service number (e.g., 611, 911), or a telephone number that can be converted into a globally routable E.164 number, as specified in section 8.3 of [RFC 8224].” From the RFC (https://datatracker.ietf.org/doc/html/rfc8224#section-8.3) Implementations MUST drop any "+"s, internal dashes, parentheses, or other non-numeric characters, except for the "#" or "*" keys used in some special service numbers (typically, these will appear only in the To header field value). This MUST result in an ASCII string limited to "#", "*", and digits without whitespace or visual separators. In looking at the examples in ATIS-1000074-E, this doesn’t mean that the + should be removed from the other SIP headers (To:, From:, etc), but apparently it shouldn’t be in the jwt of the Identity header.

Hello guys, I'm getting failed by my provider because I'm sending to them with +1 both on the headers and on the payload. My understanding is there is no mandatory format, or is there?
