// VoicemailJidRequester wraps the requesting of voicemail jids for a user.
30
// To request a voicemail jid, we first set off a query to the user's bare jid
31
// that looks like this:
34
// from='foo@gmail.com/asdf'
35
// to='bar@google.com'
37
// <query xmlns=' http://jabber.org/protocol/disco#items'
38
// node='voicemail '/>
41
// If foo@gmail.com's server supports voicemail, it'll return this, and forward
42
// the jid up to phoneapp. We do not do the second query.
45
// from='foo@google.com'
46
// to='bar@google.com/asdf'
48
// <query xmlns=' http://jabber.org/protocol/disco#items '
49
// node=' voicemail '>
50
// <item jid='bar@google.com/voicemail '/>
54
// If we get an error, we spin off a new request:
57
// from='foo@google.com/asdf'
58
// to='foo@google.com'
60
// <query xmlns=' http://jabber.org/protocol/disco#items'
61
// node='outgoingvoicemail '/>
64
// If both of these return errors, we then forward the request to phoneapp.
