I will try new isp in two weeks with better routing.
Meanwhile, is there any known latency issues if
Asterisk is behind a nat vs. asterisk with a real ip.

this is how i configured my voipjet contextin iax.conf
file

[voipjet]
type=peer
host= 216.118.117.46
secret= secret number
auth=md5
notransfer=yes
context=default
nat=yes
careinvite=no

I have just added nat=yes and careinvite=no thinking
this might be the cause of the delay, but no change

does iax maintains open communication at all times
once the call starts?
