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()
