[Freeswitch-users] dialplanhelp for callforwarding

Mon Feb 7 21:16:39 MSK 2011

There isn't a "gotoif" construct in the FS dialplan. Any time you need a
fair amount of logic in your dialplan then you should consider using a
dialplan script. You can write them in Lua, Perl, or Javascript. Personally,
the FS devs prefer Lua for dialplan scripting because it is pretty easy. I
recommend getting our book and looking at chapter 7. It's a gentle
introduction to writing simple dialplan scripts in Lua.

Remember this rule about the FreeSWITCH XML dialplan: it can do a lot but it
isn't a scripting language - it's a routing "language". Tony designed it
that way. You *can* do some logic-type constructs but I wouldn't go there
when you're still just learning everything.

The first thing you should do in translating your Asterisk dialplan to
FreeSWITCH is to write out the call flow outline. From there you can define
what aspects can be done in the XML dialplan and what can be done in your
Lua script.

The other thing I'd recommend doing is joining the #freeswitch channel on
irc.freenode.net. You can talk to people in realtime and they can help
answer specific questions.
