Hi List, I am the new guy for FreeSwitch. I am not clear what is the used of Inline execution. As per doing some tweak I found that Inline is used for set any variable for channel base like in asterisk we used double underscore( __ ). Am i right on this concept or not? Another question is how to include context in dialplan in XML ? I am reading FreeSwitch 1.0.6 for more details but still these question is not clear for me. Please help me to find out the answer of these questions. -- Thanks and regards Virendra Bhati +91-8885268942 Software Engineer E-mail-: virbhati@gmail.com Skype id:- virbhati2
Hello, Using the inline option with a dialplan action causes that action to occur immediately, as Freeswitch is parsing the dialplan. Normally, Freeswitch parses the dialplan all at once and creates a sort of "to do" list. It then changes to execute mode and actually does everything in the list all in one go. This is different than Asterisk, where asterisk executes things one at a time as it reads them. Where inline is important, is if you need to set a variable that will be referenced later on in the same chunk of code. Inline doesn't have anything to do with variable inheritance, (that is export vs. set). Inline just makes the variable change right away, so that as FS is parsing the rest of your dialplan, it has access to the variables that you are setting. Another place that inline might be useful is if you have some sort of trigger, ie. a CURL or database request. You may want that to fire when freeswitch is running through the dialplan so that it can use the return values in further decision making. As far as including contexts, it isn't as relevant since freeswitch parses everything, then executes. You can use execute_exten to achieve the same result. You would create an extension that contains your "includable" code, then use the execute_exten action to execute that block of code somewhere else. It's a bit like calling a function in a programming language. You can also use transfer as a goto routine. Be aware that transfer and execute_exten give you different results in your CDRs. Good luck! virendra bhati wrote:

Tim, that's an excellent description. Can you please find/add/update that on the wiki? It would be great if most answers on this mailing list to explain something were links to the wiki. Or even better if the wiki was so well organized and explanatory that they wouldn't even need to ask. -Avi On Tue, Feb 14, 2012 at 6:39 PM, Tim St. Pierre < fs-list@communicatefreely.net> wrote:

Indeed, Tim did a nice job of explaining that. My recommendation for updating the wiki would be to replace this section: http://wiki.freeswitch.org/wiki/Dialplan_XML#The_10.2C000_Foot_View It unnecessarily brings Sofia into the picture when discussing call processing. It would be much better if that section were re-written in a way similar to Tim's email discussion. If anyone has the FS 1.0.6 "bridge" book then you could use chapters 5 and 8 as reference material. (As long as you don't just copy and paste large blocks of text then there's no copyright issues - the facts of how the dialplan is processed are not copyrightable.) Please let me know if you guys have any questions on editing the wiki. -MC
