Hi Karsten,

Thank you for the reply. You are correct. I am trying to retrieve billing information from a basic call. I am calling lua script in the dialplan. When a call comes in, FS hands it over to lua script for processing.

</condition>

</extension>

</include>

I did the same thing with ESL where I listened for CHANNEL_ANSWER and CHANNEL_HANGUP events then fetched answer and hangup times and that worked just fine. I would like to do the same thing with lua.

Thanks

Subject: Re: [Freeswitch-users] Wait for ANSWER/HANGUP events in Mod lua

Hi Sam,

you should be more verbose what you currently doing. There a many ways to call an lua script in FS (in the dialplan, as startup-script, as dialplan-binding etc).

Sounds like you want to fetch some kind of billing informations.

I am using Mod lua for call processing on the FreeSwitch. I would like to wait for some events such as CHANNEL_ANSWER and CHANNEL_HANGUP in order to get the answer time and hangup time. Basically, something like

Wait for event CHANNEL_ANSWER or CHANNEL_HANGUP

If (event_name = “CHANNEL_ANSWER”) then answer_timestamp = getHeader(“Caller-Channel-Answered-Time”)

If (event_name = “CHANNEL_HANGUP”) then hangup_timestamp = getHeader(“Event-Date-Timestamp”)

The session:getState() described in module lua gets the call state but not the channel state. For instance, ‘CS_EXECUTE’ is the channel state when it is executing a dialplan not when the call is answered.

Is there a way to wait for channel events such as CHANNEL_ANSWER and CHANNEL_HANGUP in order to retrieve answer and hangup timestamps for a call?

Any input is very much appreciated.

Thanks.

Sam
