How iax trunk

--------- In A place I have (asterisk compiled) :

[30200]
type=friend
secret=30200
host=192.168.254.58 ;(ip of host B)
context=total

[IAX-B]
username=20200
type=peer
secret=20200
qualify=yes
host=192.168.254.58
context=total

--------- In B place I have (freepbx) :

[20200]
type=friend
secret=20200
host=10.3.251.58 ; (machine A)
context=from-internal

[IAX-A]
username=30200
type=peer
secret=30200
qualify=yes
host=10.3.251.58
context=from-internal

I can’t do calls …and I have (logs of B place) :
Nov 5 23:37:11 NOTICE[21812] chan_iax2.c: Rejected connect attempt from 192.168.254.58, who was trying to reach '028@'
Nov 5 23:37:11 WARNING[21812] chan_iax2.c: Call rejected by 192.168.254.58: No authority found
Nov 5 23:37:11 DEBUG[21812] chan_iax2.c: Immediately destroying 17, having received reject

I am trying the tips from voip-info.org/wiki/view/Aste … al+servers, but i can’t do a IAX Trunk between A and B .
How and where I should be configure the dial plan in order to make a IAX Trunk. AND / OR I need other parameters ?

Thanks in advance .

From B to A is OK :
