[asterisk-users] Asterisk Realtime PJSIP - slow output on "pjsip show xxxxx" commands

Hi all!

I have an Asterisk instance (15.4.1) with a MySQL DB in realtime configuration (using MySQL ODBC connector).

I noticed, that when I issue “pjsip show endpoints” in the CLI this takes forever (on average about 1 minute with 1029 entries in ps_endpoints table).
If I query the database over the same ODBC connector with isql, this takes less than a second.

I have enabled caching in sorcery.conf but it doesn’t really help (at least not concerning the output of “pjsip show xxxxx” commands).

Any idea what might be causing this and how I can optimize it?

With best regards

I also just tried adding this:

 same => n,Set(SIP_CODEC_INBOUND=g722)

We want to record inbound channels at 16kHz, but send only 8kHz to our peers. I've set our default profile in sip.conf to disallow all but g722, and the peers disallow all but ulaw. We have a proxy in front of Asterisk that is configured to disallow all but G722 also.

My test calls show inbound to the proxy is recorded at 16kHz, inbound in Asterisk is only 8kHz, and the peers receive 8kHz. So the only thing not working is Asterisk's sampling rate on inbound, and it seems to be downsampling.

After a lot of web searching, I can't find any explanation of why we're not getting 16kHz for G722. We're using Asterisk 14.7.6.
