[asterisk-users] Asterisk 16 Certified 16.8 and MagicJack Incoming Calls

[Chris Dos]

It seems that if there is a pause in the auto attendant longer than a second
this problem occurs.  I have this for an extension in my extensions.conf file:

exten => 2799,1,GotoIf($["${CALLERID(num)}" = "${EXTEN}"]?500)
exten => 2799,2,Dial(PJSIP/${EXTEN},14,tr)
exten => 2799,3,Dial(PJSIP/${EXTEN},1,tr)
exten => 2799,4,BackGround(abandon-all-hope)
exten => 2799,5,BackGround(dial-here-often)
exten => 2799,6,Wait(2)
exten => 2799,7,BackGround(gambling-drunk)
exten => 2799,8,BackGround(you-seem-impatient)
exten => 2799,9,BackGround(nobody-but-chickens)
exten => 2799,10,BackGround(tt-somethingwrong)
exten => 2799,11,BackGround(tt-weasels)
exten => 2799,12,Voicemail(${EXTEN},ug(15))
exten => 2799,13,Voicemail(${EXTEN},bg(15))
exten => 2799,14,Hangup
exten => 2799,500,VoicemailMain(${CALLERID(num)})

If I change the Wait to 1 the MagicJack will hear everything.  If I change it
to 2, nothing is heard from that point on.
