[asterisk-users] IAX2 trunking with Older Asterisk version ?

[Tharanga]

Hi All,

Is it possible to make a IAX2 connection between asterisk 1.6.1.0 , and 
asterisk 1.2.14 ?

i tried to use a IAX2 connection between version 1.2.14 and 1.6.1.0 but 
it gave an error -

1.2.14 End  - Error Msg
WARNING[8313]: chan_iax2.c:7103 socket_read: Call rejected by 
147.120.203.71: No authority found

1.2 END , IAX.conf

[trunk14]
type=friend
host=147.120.203.71
secret=test123
context=sip,sip2,sip3
permit=0.0.0.0/0.0.0.0


1.6.1.0 End - Error Msg
NOTICE[9854]: chan_iax2.c:8782 socket_process: Rejected connect attempt 
from 147.120.203.69, who was trying to reach '4567@'

what could be the problem ? do i need to have the same asterisk versions 
both side ?

Thanks,
Tharanga
