[asterisk-users] Hangup() not working for handsets using pls transport?

Fri Feb 5 19:29:14 CST 2021

Thanks Jashua for the suggestion.  To find out if the issue was only
limited to the softphone that was using tls transport (SOFTPHONE_B on ext
103, a linphone running off my MBP), I also turned one of the hard phone
(0000f30A0A01 on ext 100, a Yealink T32G) into using tls transport.  It
behaves similarly to the linphone in that the Hangup() call in dialplan is
silently ignored, and the handsets would alway appear as busy/unavilable.

Here're the relevant part of my /etc/asterisk/extensions.conf:

[globals]

; General internal dialing options used in context Dial-Users.

; Only the timeout is defined here. See the Dial app documentation for

; additional options.

INTERNAL_DIAL_OPT=,30

RP_Yealink = PJSIP/0000f30A0A01

RP_Cisco = PJSIP/0000f30B0B02

RP_HMBP = PJSIP/SOFTPHONE_A

RP_OMBP = PJSIP/SOFTPHONE_B

[sets]

exten => 100,1,Dial(${RP_Yealink},10,m)

        same => n,Playback(vm-nobodyavail)

        same => n,Hangup()

exten => 101,1,Dial(${RP_Cisco},10)

        same => n,Playback(vm-nobodyavail)

        same => n,Hangup()

exten => 102,1,Dial(${RP_HMBP})

exten => 103,1,Dial(${RP_OMBP},10)

        same => n,Playback(vm-nobodyavail)

        same => n,Hangup()

exten => 110,1,Dial(${RP_Yealink}&${RP_Cisco})

exten => 200,1,Answer()

   same => n,Playback(hello-world)

   same => n,Hangup()

  Here're what pjsip logger captures when using the tls softphone (on ext
103) to call ext 101 (Hello World!). I had to click the hanup button on the
linphone some 15s later to terminate the call.

Here's what happens when using a udp hardphone (on ext 101) to call a tls
hardphone (on ext 100). It went straight to the no-body-around message w/o
ringing and on-hold music.
