Hi,

%2A is not the ASCII format of *, it is the escaped (see RFC 3261).

And, the syntax allows both * and #, so no need to escape (in fact, it is not even possible to escape in this case):

             tn-spec =  1*tn-char
             tn-char = "#" / "*" / DIGIT

Also, note that RFC 8224 does not define the syntax of the To header field - that is done in RFC 3261. The telephone number described in Section 8.3 of RFC 8224 will be included in the PASSPort (RFC 8225).

Regards,

Christer

Good Morning.

This may not be the correct process, so let me know if I should ask this in a different forum.

I had a question regarding section 8.3 when it comes to * and # handling.  Is this stating that when a * or # proceeds a digit string (i.e. *55), it should be in ASCI Format for the * (i.e. %2A)

<image001.png>

So Instead of this:

To: sip:*55;phone-context=ims.mnc420.mcc312.3gppnetwork.org@ims.mnc420.mcc312.3gppnetwork.org;user=phone

It should be this
