well i have asterisk 1.4.2 - i have a intermittent problem looks like related to codecs.
My calls sometimes are connected fine, sometimes i get one way audio, sometimes the system just hangs up on me like in the following order:

Call on SIP/Euras-083862c8 left from hold
-- SIP/Euras-083862c8 is making progress passing it to SIP/72269588-0837c588
-- Call on SIP/Euras-083862c8 left from hold
-- SIP/Euras-083862c8 answered SIP/72269588-0837c588
-- AGI Script a2billing.php completed, returning 0

i disabled all the codecs except g729.
Whenever i use did for calling cards or sipura to make calls i cannot get consisted g729 usage - sometimes system is using it , sometimes it is using something else. I have 10 g729 channels purchased. i have sip.conf set to g729 only, my did's support g729 and my sipura phone set only for g729.

Any ideas????

Seems like problems started when i upgraded to 1.4.1 from 1.2.14
I started having sip brigding issues and audio problems. Is anyone else having these problems????

Did you try to ask it on the asterisk/digium forum?

I think I read about some issues with 1.4.1 ... and 1.4.3 ... that might make it better, but you know - there's a reason the latest release at first is called "bleeding edge" instead of "leading edge". I'd assume 1.4.3 would be more stable version of 1.4 though.

what reason did you have for upgrading from the 1.2 ?? I'd guess jitter control?

1.4 runs cleaner and better audio (config dependent). Ran a2billing very well until recently when a software upgrade of the underlying fedora 5 was done, problems as described with codec/SIP negotiation arose (upgrade may have played a role).

Fortunately 1.4.3 was released and installed, all have settled down again.

To answer your question 1.4.3 should work for you.

Should note though that this version of a2billing 1.2.3, is used with a newer phpagi version with minor code changes. DTMF is improved and possibly other performance improvements.

Asterisk does not support comfort noise or VAD so it must be turned off on your providers end or you will have one way audio and other call negotiating issues. The hard fact is that some providers can't turn it off even if they wanted to because they are just a proxy.

If you have VAD/Comfort noise issues find a provider who does not send VAD.

The Better providers have a code that allows you to turn it off eg. Dial SIP/TRUNK/xxxx15453445634

I am experiencing one way audio on some of the calls. I'd say about 20% and initially thought it was carrier but I'm having it accross all carriers. We do not have any NAT. We have Asterisk 1.4.19 on a i686 running Linux Centos 5.1 and A2billing 1.3.3. Any suggestions appreciated.

Added after 3 hours 24 minutes:

I checked the Asterisk website and the latest stable version is 1.4.22 and there is an option of DAHDI instead of Zaptel. Is anyone running 1.4.22 with a2billing 1.3.3? Thanks.

No, we're not behind a NAT and 80% of calls go thru without this problem.

Is anyone running 1.4.22 with a2billing 1.3.3? I plan on using it, my only concern is does Dead AGI work with this version and how will it affect the T1 Card that we have running.

We just installed the 1.4.22 and DAHDI. So far seems to be working correctly. I'll compare my CDR to that of the carrier later to see if we're not loosing anything b'cos of dead agi. I will let u know when I do.

CLI below.

-- Executing [5959@default:1] Goto("DAHDI/2-1", "a2billing|5959|1") in new stack
-- Goto (a2billing,5959,1)
-- Executing [5959@a2billing:1] Answer("DAHDI/2-1", "") in new stack
-- Executing [5959@a2billing:2] Wait("DAHDI/2-1", "1") in new stack
-- Executing [5959@a2billing:3] DeadAGI("DAHDI/2-1", "a2billing.php|1") in new stack

After the upgrade the server crashed after 12 hours. /var/log/syslog show a soft lock up. This happened the last time we upgraded and added the T1 card. Digium had given us a patch to run to fix it. This issue of kernel panic is related to Digium's TE220 PCI Express card with echo cancellation.

upgrade included
dahdi-linux-2.1.0
dahdi-tools-2.1.0
asterisk-1.4.22

Just sharing info if you ever run into it.
