Call reservation on busy

Redmor · March 18, 2022, 10:46am

Hello,

I’ve read about Camp-on functionality to place a call reservation if an extension is busy.
I can’t find it anymore in FreePBX Advanced settings, it has been replaced?

lgaetz · March 18, 2022, 10:51am

Yes, campon was deprecated. It was never updated to work with pjsip.

Redmor · March 18, 2022, 10:53am

So there’s no way to make it with something else?
If I go back to chan_sip I can use it with FreePBX 16?

lgaetz · March 18, 2022, 1:55pm

The old campon module still can be installed on FreePBX 16, but the code hasn’t been touched since FreePBX 13. No idea if it still works or not. I would advise against spending your time on something that is known not to work with pjsip.

How can I install it?

You shouldnt. Chan_sip is deprecated and being removed from Asterisk next year. You shouldnt do anything that depends on it at this point

Redmor · March 23, 2022, 1:03pm

Do you have any documentation stating the remove of chan_sip?
I don’t want to install it either, but I need to prove to my customer it is deprecated.

               The ast_channel_cache_all() and ast_channel_cache_by_name() functions
               now returns an ao2_container of ast_channel_snapshots rather than a
               container of stasis_messages therefore you can't call stasis_cache
               functions on it.
               The ast_channel_topic_all() function now returns a normal topic,
               not a cached one so you can't use stasis cache functions on it either.
               The ast_channel_snapshot_type() stasis message now has the
               ast_channel_snapshot_update structure as it's data.
               ast_channel_snapshot_get_latest() still returns the latest snapshot.
            
            
chan_sip
            ------------------
             * The chan_sip module is now deprecated, users should migrate to the
               replacement module chan_pjsip.  See guides at the Asterisk Wiki:
                 https://wiki.asterisk.org/wiki/x/tAHOAQ
                 https://wiki.asterisk.org/wiki/x/hYCLAQ
            
            
func_callerid
            ------------------
             * The CALLERPRES() dialplan function, deprecated in Asterisk 1.8, has been
               removed.

I could probably find more. From an Asterisk perspective I’ve done presentations at Astricon about it, tweeted about it, posted on the mailing list. Asterisk will even warn when it loads these days.

Going to be straight up here. You actually haven’t said what the goal is here. All you said is “I read about camp on”. What are you trying to do actually? Because there may be solutions for what you are trying to do.

Redmor · March 23, 2022, 1:56pm

I was actually trying to do what camp on does.
When an extension is busy I want to receive a call from it when it is available again, or even just a message “Extension 123 is available again”

comtech · March 23, 2022, 3:57pm

Have not tried this, but seems like it could work

Turn off call waiting
Change the extensions busy treatment to go to a custom context that builds a call file that will call the customer and play a message or transfer to the original extension, and name it with the extension number + epoch time
7.2. Call Files
On hang-up, run a script that looks in the folder you placed the call file in and grabs the oldest call file that contains that extension number in the file name and moves it to the outgoing folder to place the call
How to run the script after the call ends?
Thank @lgaetz
