Hi, as discussed in sip-implementors[1] it seems that the use of TEL URIs in SUBSCRIBE requests is not considered in RFC 3856.
RFC 3856, Section 5 "SUBSCRIBE messages also contain logical identifiers that define the originator and recipient of the subscription (the To and From header fields). These headers can take either a pres or SIP URI." IMO it should be permitted since a SUBSCRIBE request would be routed the same way an INVITE request would.
