[asterisk-bugs] [JIRA] (ASTERISK-16846) [patch] [branch] IAX2 on Realtime doesn't resolv DNS lookups

[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-16846?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=225146#comment-225146 ] 

Matt Jordan commented on ASTERISK-16846:
----------------------------------------

Through some ridiculously mysterious notes, this should have been fixed sometime around when 1.8.9 was released. Looking at the ChangeLog, I suspect it was this commit with no underlying issue:

	* channels/chan_iax2.c, include/asterisk/acl.h,
	  channels/chan_skinny.c, channels/chan_h323.c, main/acl.c: Fix
	  calls to ast_get_ip() not initializing the address family.

(Side note: forensics is *really* hard when no one writes down what they were working on, which issues, commit numbers, etc. Sheesh. :-( )

As it is, I suspect this is fixed. I'm going to close this out as Suspended, as 1.8 no longer receives bug fixes. If this is still an issue in a supported branch of Asterisk, please comment here and I'll be happy to reopen it.

> I've been using Asterisk 1.6.2 with Realtime.
> Today I installed a new machine with Asterisk 1.8.0 and use the same Database for Realtime.
> Everything works just fine on Asterisk 1.6.2, I mean when I sent a call to a provider using IAX2 protocol it works just fine, but the same doesn't happen on Asterisk 1.8.0, only on Realtime.
> I put the same parameters on iax.conf and it's worked just fine.
> ****** ADDITIONAL INFORMATION ******
> Here are the Debug from Asterisk 1.8.0. I have changed the name of the provider to IAXPROVIDER.
