Cisco/Tandberg sip connection PJSUA

Hello World!

Configuration: Ubuntu18.04LTS, Jitsi-meet with JWT-token auth, jibri with recording. All working fine.
I need to invite cisco sip client in to Jitsi-meet conference. I compiled pjsua, put to configurarion file my sip credentials and pjsua calling to my endpoint terminal and Cisco Jabber Video clients, but i don’t have audio and video on both side. I do not understand what devices I need to specify as audio and video devices.
And if “recorder.mydomain” is hiddendomain, i dont see in jitsi-meet conference new client after calling.
I tried to downgrade version of Chrome and ChromeDriver to 75 and 71 version. Did not help.
