[Asterisk-Users] dial (iax/X&sip/y) get y fraction earlier

[Luki]

> exten => _06.,1,Dial(IAX2/X/${EXTEN},30,r&SIP/${EXTEN}@Y.Y.Y.Y)

Even that's incorrect. It should be:
exten => _06.,1,Dial(IAX2/X/${EXTEN}&SIP/${EXTEN}@Y.Y.Y.Y,30,r)

See:
[Description]
  Dial(Technology/resource[&Technology2/resource2...][|timeout][|options][|URL]):

Also, see the Wiki or this mailing list regarding the use of the 'r' option.
