If I can get some clear documentation on how the threading model is supposed to work, what’s responsible for what, how a module can be re-entrant, etc. etc. I’ll be happy to make nice clear managed code to make it easy.

 

Unfortunately, last time I got into it, it seemed to be rather complicated and not perfectly understood. And control modules were supposed to be of the “set a command and get lost” variety, and not really “own” the thread/call. There were also futher complications depending on if the call was bridged, and if it was bridged with media or not, and so on.

Subject: Re: [Freeswitch-users] Problem with originated calls hanging in CS_SOFT_EXEC state

 

Yes, they should be deprecated. Mod_managed has changed a lot over the years, and a lot of those things are still left over from the days when it was either single app domain, or there were no other for controling or collecting data form outbound legs.

 

One of the things i forgot to mention in my last reply, that is if you want to control an outbound legs completly form managed code, using the session object it is a lot easier to just do "Session.ExecuteString("originate channel/params &managed(yourclassname")". Then you can handle it just like at was an inbound call, and not even worry about clean-up.

 

The places you may want to use the hooks are for applications where you need to originate a call from API or other context, not actually have to control the call via managed code, but need to know about the outbound leg (execute_on_originate) where you can stash UUID, and other information about the leg, or get easy notification of call being answered/terminated (api_on_answer,api_hangup_hook). With both of these API hooks, set in the "originate" api call, you can also pass variable arguments that are expanded when they are executed {origination_nested_vars=true}. Does anyone know if that is documented on the wiki? I can't find it.

Subject: Re: [Freeswitch-users] Problem with originated calls hanging in CS_SOFT_EXEC state

Thanks Anthony! I found the ManageSession methods by looking at the code that is exposed via swig.

 

Using  "execute_on_*" hooks seems to be the proper procedure, it needs to be documented on the wiki. There is virtually no documentation to originate a call for mod managed on the wiki. I will correct that if I can get wiki access.

 

I will illustrate your solution using "execute_on_originate" as the preferred solution. There are also several "execute_on_*" hooks that would work. 

 

Should ManagedSession.OriginateHandleHangup and .Originate() methods be deprecated to discourage their use in further releases? Or at least some comments in the code that point people to look at execute_on directives. Does Java have this same issue?

 

Anthony,Glad I found a bug by doing the wrong thing.... sorry for making work for ya!

 

I cannot say enough about how responsive Anthony and the community has been about this issue. THANKS!

This may be a bug, but ManagedSession really is not the right way to do this

from API context. Because of the APP_DOMAIN issue its much easier to just do

Api.ExecuteString("originate ... "). If you need to get to the "managed

session of the leg you have two options:

 

For getting to it before the originate set the variable execute_on_originate

to call a managed AppPlugin, or:

 

For getting results at the end of the call in API code, set the variable

API_HANGUP_HOOK.

 

Both of these methoods are much easier to do from API context in

mod_managed, and you won't have to worry about crossing app domain

boundries, and you won't have do do any cleanup on the leg.

use lines like this to follow the code paths when you call destroy

switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_CRIT, "BLAH\n");

 

The part I am concerned with is when you call destroy you dont see the

log line you should:

 

switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(session),

SWITCH_LOG_DEBUG,

"%s destroy/unlink session from

This makes me wonder if you are some older version...
