• There is not enough information for anyone to really help or comment on this. Dialplan and IAX2 configuration on both sides of the trunk?
  CLI output on both sides with iax2 debug enabled?

• It is very simple:

  Local Asterisk, iax.conf:

  [clinic_server]
  type=friend host=dynamic context=internal disallow=all allow=ulaw allow=alaw requirecalltoken=no callgroup=1
  pickupgroup=1

  extension.conf:

  exten => 4,1,Dial(IAX2/home_server:xxxxxxxx@${clinic_server}/${EXTEN},60,rw)
  exten => 4,n,Hangup() Remote Asterisk iax.conf:

  [home_server]
  type=friend host=dynamic secret=xxxxxxxx context=extensions disallow=all allow=ulaw allow=alaw callgroup=1
  pickupgroup=1

  Remote extension.conf:

  exten => 4,1,Dial(SIP/4,15,trw)
  exten => 4,n,GotoIf($[“${DIALSTATUS}”=”BUSY”]?vmail:line2)
  exten => 4,n(line2),Dial(SIP/54,20,rw)
  exten => 4,n(vmail),Voicemail(4)
  exten => 4,n,Voicemail(4)
  exten => 4,n,Hangup()

• You have no internal context in your dialplan. But in your iax.conf you specify internal as your context.

• I forgot to write, the remote asterisk has:

  [internal]
  … include => extensions

  [extensions]
  exten => 4,1,Dial(SIP/4,15,trw)
  exten => 4,n,GotoIf($[“${DIALSTATUS}”=”BUSY”]?vmail:line2)
  exten => 4,n(line2),Dial(SIP/54,20,rw)
  exten => 4,n(vmail),Voicemail(4)
  exten => 4,n,Voicemail(4)
  exten => 4,n,Hangup()

  So on the remote asterisk there is context [internal]

  I even noticed starting asterisk-16.30 is much slower than starting Asterisk-16.16
