Did not figure out what the exact problem is.

2

You haven’t provided your dial plan, or logging from which it can be inferred.

As the message says, no-one answered the [B side] call in 20 seconds. The 20 seconds will be whatever you set as the maximum time to answer when you invoked Dial. As the default is unlimited, you must have set something.

3

Am I need to increase the time in dial plan, which is currently 20?

Either increase it, or if you don’t want the message with any number of milliseconds, remove it entirely. Only you know what if any timeout is needed.

5

Is it the same reason for " Auto fallthrough channel"?

6

It is the reason for the NOANSWER in the auto-fallthrough message, but the message itself is normal. It just means you ran off the end of the dialplan with the current default behaviour of ending the call, rather than the old one of giving dial tone for another try.

7

Okay.

In my iOS application, I’m sending a voip push token to open the app while it’s kill mode and once user accept the call then app will registering the Ext and request to join the channel.
this flow is working prefect fine if user accept the call with in couple of seconds, But if user will accept the call after 12 to 15 seconds then it does not connecting to the channel as dial plan execution was already been completed and it does not found a register ext.

Is there any solution to for this?
Or is there any way to call dial plan manually or call the dial plan once ext gets register?

8

You can check the device state to see if it is registered, or analyze the failure, to see if that was consistent with being unregistered. In both cases, looping and retrying.

However, failed to pick up is not a failure you would get for an unregistered endpoint. You would get an immediate unavailable condition.

9

Yes, you are right!!.

I’m getting the channel “UNAVAILABLE”.

I have added the below code to the dial plan if its get’s failed for any of the below reasons.

I simply want to execute retrial 5 times in 3 seconds intervals for PJSIP extensions if Ext is not registered.

exten => _X!,n,Set(DIALSTATUS=${IF($["${FM_DIALSTATUS}"="NOT_INUSE"&"${DIALSTATUS}"!="CHANUNAVAIL"]?NOANSWER:${IF($["${DIALSTATUS}"="CHANUNAVAIL"|"${FM_DIALSTATUS}"="UNAVAILABLE"|"${FM_DIALSTATUS}"="UNKNOWN"|"${FM_DIALSTATUS}"="INVALID"]?CHANUNAVAIL:BUSY)})})
exten => _X!,n,GotoIf($["${DIALSTATUS}" = "CHANUNAVAIL"] ? RetryDial(please-wait,5,3,PJSIP/${EXTEN},10,d))

But, Seems it does not work.

10

The SET assigns to a dead variable. It makes no sense.

Whilst I believe that DIALSTATUS is real variable and, therefore, can be setting is confusing, and, in this case, nothing will read it between when it is set and when Dial sets it.

Also, this looks like a case where _X! can end up matching a special extension, so is unsafe.

11

Variables prefixed with AMP are normally part of FreePBX, which is not supported on this forum.

13

Yes, But I just want to execute the retrydial. which is not working right now.

Can you pls guide for this?

is retrydial syntax correct or Am I need to pass channel over there rather than ext?

14

Your question is using FreePBX terminology. The documentation says:

dialargs - Same format as arguments provided to the Dial application

Dial expects a dialstring, which is what you seem to have. It never expects an Asterisk extension name.

15

You haven’t provide a log demonstrating this, although it is difficult for us to interpret logs created by FreePBX systems, so I can’t guarantee that anyone will try on this forum.
