Description:Upgraded system from 1.2 to 1.6.0.10
PSTN access via chan_dahdi.
System has IAX2 phones connected. (phones from allnet 7960)

ACTION:
1.) incoming call from PSTN to IAX2 phone.
2.) IAX2 phone is ringing
3.) IAX2 phone answers call.

EXPECTED RESPONSE:
1.)
2.) phone rings
3.) call is connected, conversation

ACTUAL RESPONSE:
1.)
2.) phone rings
3.) call is connected, but called user hears ringing tone

It seems that the IAX phone interpretes the RINGING command even when the call has been answered.
Nevertheless, Asterisk should not send the RINGING command !

****** ADDITIONAL INFORMATION ******

function ast_bridge_call sends the RINGING indication to the IAX2 peer. chan_iax2 blindly accepts this info and sends it in iax2_indicate to the iax device.

Now that the 1.6 is EOL is this patch going to be integrated or not ?
By: Sean Bright (seanbright) 2012-02-20 12:42:00.965-0600

Not into 1.6.0, 1.6.1, or 1.6.2, no.  I'll review it for 1.8 and upwards.
