I look after a call center’s asterisk system which I built and have been running for a couple of days. When I checked the logs, I found that I encounter this error a couple of times every minute. Most calls do get placed, but there ARE calls that does not… Mostly due to this error i guess.

I noticed that there’s no translator type for PJSIP Channel to none? why is there a none there? Is it because its over the capacity and there aren’t any channels available at these moments? Or is it just some error, and if so, how can I fix it?

and my SIP Trunk uses g729 codec. so when i set up the trunk in FreePBX, i did select g729 in the advanced menu, and a couple others too… you know, just in case!
