[Serusers] Which SIP messages types use lookup("location")?

[Klaus Darilion]

Hi all!

Every message which is in-dialog should be forwarded without lookup().

That means, for the first INVITE you make a lookup(), but if there are 
othere messages within this dialog (re-INVITE, INFO, REFER, ACK, BYE, 
MESSAGE ...) you don't use lookup.

dialog-creating requests and messages which are always outside a dialog 
will use lookup(), e.g.: INVITE, SUBSCRIBE, MESSAGE, PUBLISH

For NOTIFY: these belong to an existing dialog, so there is no need use 
lookup().

regards,
klaus
