Description:Hi,

I have a setting were i have 10 pjsip endpoints 100X. in the dialplan i have a section to pickup ringing channels.
{noformat}
> exten = _900X,1,PickupChan(PJSIP/100${EXTEN:3:4},p)
{noformat}
Use case: 1002 calls 1004. while 1004 ringing, 1001 dials 9004 and picks up channel. here is the pjsip list endpoints before and after the call is hung up.

The call count of 1001 is not decreased. after a few repetition of the same use case here is the state --
{noformat}
>  Endpoint:  <Endpoint/CID.....................................>  <State.....>  <Channels.>
>  Endpoint:  1001/1001                                            **Not in use    5 of 1**

{noformat}
Although 1001 is configured to device_busy_at=1, i can still call it!

I have a application that decides endpoint is busy through ari call to get endpoint and find channel_ids.size

it does not decrease unless asterisk is restarted.

Tested in asterisk 13.8-cert4 and 15.2.1. fails in both cases.
