Description:We have 2 IAX trunks between head office and 2 branch office, over a 5Mbit private ip network.

Each time a call hangs up on the same trunk as other calls, the other calls hear an annoying click.

When a 2nd call joins the trunk, no clicks are heard.  

Call quality while talking is near perfect with so much bandwidth, we are using alaw codec.

I could have sworn I saw another issue filed that described the same thing as this, but I can't seem to find it right now.

'acknowledged' what now?

This is probably more severe than initially reported, as I'd only heard it before deployment, but now the deployment is done, with the trunks between offices being busy, it's actually quiet annoying.

I've acknowledge that based on your description, this is probably an actual issue that needs to be moved forward by a developer. The more information you can provide the better, however resources will resolve the issue as time permits.

Is this still a problem?
By: Alec Davis (alecdavis) 2011-05-12 21:34:05

Not any more that worries us.

Same test between same sites, now with Asterisk 1.8.2 and SVN-branch-1.8-r315673M
