Issues with Paging in asterisk

dmsherazi · March 21, 2019, 12:12pm

I am trying to implement the following dialplan where if someone calls 8XX asterisk will page extension 1XX. The Devices that register for 1XX have been set to auto answer paging/intercom.

exten => _8XX,1,NoOp(Testing calls to autoanswer)
same => n,Set(number=${EXTEN:-2})     
same => n,Page(${PJSIP_DIAL_CONTACTS(1${number})})                    
same => n,Hangup()

So when I dial 804 it should page the devices registered with endpoint 104 and the device should autoanswer, on contrary if I dial 104 it should dial the PJSIP contacts for 104 and the device should not auto answer as autoanswer is selected for paging only. In my situation, the device won’t auto answer 804.

here is what I get on the cli

The softphone from where I dialed starts the call timmer but the phones registered to 104 keeps ringing

You don’t seem to have set any SIP headers that might cause the device (not extension) to answer. It didn’t answer.

dmsherazi · March 21, 2019, 12:44pm

How to setup them? Would this work?

Set(PJSIP_HEADER(add,answer-after=0)

david551 · March 21, 2019, 12:46pm

There isn’t an official standard for such headers and I am not sufficiently familiar with PJSIP to be sure that the way of setting the header is correct, but it probably is.

dmsherazi · April 2, 2019, 2:23pm

I tried the following

exten => _8XX,1,NoOp(Testing calls to autoanswer)
same => n,Set(number=${EXTEN:-2})  
same => n,Set(PJSIP_HEADER(add,Call-Info: answer-after=0)   
same => n,Page(PJSIP/102,ib(paging_handler^addheader^1))                    
same => n,Hangup()  


[paging_handler]
exten => addheader,1,Set(PJSIP_HEADER(add,Call-Info)=;Answer-After=0)
same => n,Return()

but am getting this error

WARNING[17666][C-00000003]: app.c:403 ast_app_expand_sub_args: Cannot expand 'Gosub(paging_handler,addheader,1)' arguments.  The app_stack module is not available.

I am using Openwrt and Asterisk 15

jcolp · April 2, 2019, 2:41pm

The app_stack module does not appear to be loaded, which is needed.

dmsherazi · April 9, 2019, 10:54am

I am able to make the paging call now but I am facing an issue . the audio works one way and the video doesn’t work
.
103 is a sof-tphone and 102 is the IP Phone that has auto answer enabled when there is a paging call.
below is the verbose log of a normal call from 103 to 102.

in the above case the in paging there is one way audio and no video

jcolp · April 9, 2019, 10:55am

It’s on purpose that audio is one way, as for video I doubt anyone has ever tested paging with video. I kind of doubt it would work. It was strictly done for audio purposes.

dmsherazi · April 9, 2019, 10:56am

Is there a way to make two way audio? Indeed I need to make the phone behave as an video intercom.

jcolp · April 9, 2019, 11:05am

The documentation for Page[1] shows a full duplex option. As for video, there’s no options or anything for it. It’s just not something anyone has done with Page.

I think you are confusing Paging with the proprietary auto answer headers supported by some phones. The phone cannot distinguish between Page and Dial,so you can force an autoanswer, where supported, for Dial, and get full point to point call media capabilities.

Just remember that anyone else who can access the phone can do this, as well.

dmsherazi · April 9, 2019, 11:37am

Changing Page to Dial in the below results in Normal call and the Phone doesn’t auto answer

dmsherazi:

exten => _8XX,1,NoOp(Testing calls to autoanswer)
same => n,Set(number=${EXTEN:-2})  
same => n,Set(PJSIP_HEADER(add,Call-Info: answer-after=0)   
same => n,Page(PJSIP/102,ib(paging_handler^addheader^1))                    
same => n,Hangup()  


[paging_handler]
exten => addheader,1,Set(PJSIP_HEADER(add,Call-Info)=;Answer-After=0)
same => n,Return()

jcolp · April 9, 2019, 11:40am

Both Dial and Page operate the same way fundamentally, if it’s not working then it’s likely your configuration (for example Dial doesn’t have the same argument format as Page).

david551 · April 9, 2019, 12:04pm

Although it is relatively new, both Page and Dial have b optiions. DId you include the b option on Dial?

dmsherazi · April 9, 2019, 12:10pm

As @jcolp said the Dial argument format is different.

same => n,Dial(PJSIP/1${number},,ib(paging_handler^addheader^1))
