[Serusers] ENUM tel records

Juha's ENUM lookup routine currently looks up the e164.arpa tree for a phone number and searches for a sip record, which is returned and used to rewrite the current uri. ENUM also allows tel: records amongst others. What, if anything should be done with those, and how should they be treated relative to sip records? I would assume a tel: record could be interpreted as a kind of call forward, which could be arbitrarily staged. One way of handling this could be to explicitely look for tel records with, e.g., an argument to enum_query() to have any tel records rewrite the current uri, and then go on to look up the result (maybe recursively which requires a loop counter and an abort condition). so the resolution could look like while (loopcount--) { enum_query("tel"); enum_query("sip"); } what do you think? -Michael
