So PRACK/ACK/CANCEL/BYE/SUBSCRIBE/NOTIFY ( in-dialog)/REFER have to have the same from/to header as initial INVITE which is allowed to have TEL URL. 2)From RFC 3396 and 3261 ,I concluded that tel: URI can be present in INVITE and REGISTER request in following headers. For INVITE tel: uri can be present in "request URI" , "From header", "TO header". >From Register tel: URI can be present in "Contact header". for privacy it can also be present in p-preferred and p-asserted header. besides this ,is it possible to have <tel:> uri in any other header(e.gRoute, record-route ,Via )? >> It should also be possible to have TEL URIs in Diversion Header.
