Unknown or unavailable item requested - QoS Variables Missing

Asterisk Asterisk Support

We are currently using asterisk version 13.14.0 with a freepbx implementation and are keenly interested in QoS. The following are our configs

We are able to get QoS stats on “from-trunk” context but are not able to get from any other dial plan.

We get the following errors on asterisk full log

Kindly assist.

That is using a PJSIP channel which uses different parameters to the CHANNEL dialplan function for extracting that information. They are documented on the wiki under the PJSIP technology[1].

@jcolp Thank you for your prompt response.

The parameters I have used on the extensions_custom.conf are similar to what you have in the link.

Could it be a positioning issue or syntax?

Kindly let me know how you would get QoS stats for for example rxjitter - Received packet jitter.
exten => ???

Cheers

They are similar, but not what PJSIP supports - thus the unknown or unavailable item warning. Here’s an example:

${CHANNEL(rtcp,rxjitter)}

@jcolp, Many many, thanks that worked!!!

Now I just need to figure out why I get stats from calls that go to voice mail but not from calls that have been picked.

Cheers
