[asterisk-users] 183 Session in Progress. Disconnecting channel for lack of RTP activity

Today I faced a problem. Please help to solve this problem.

Asterisk 13.7 (chan_pjsip) & Zyxel Keenetic Plus DECT, firmware 
v2.06(AAGJ.9)C1

Outbound call from Zyxel Keenetic (pjsip endpoint) to PSTN (pjsip trunk).
Call using early media (183 Session in progress) and rtp_timeout=10.
After 10 seconds: [2016-12-16 13:53:15] NOTICE[6654] 
res_pjsip_sdp_rtp.c: Disconnecting channel 'PJSIP/xxx-0000027b' for lack
of RTP activity in 10 seconds

SIP dump is attached.

According to [1] before called user agent send OK or ACK there is one 
way SDP.
In sip dump (attached) i didn't find such SIP packets. Whether that call 
was canceled due to RTP inactivity?

Any help is welcome.

[asterisk-users] 183 Session in Progress. Disconnecting channel for lack of RTP activity

This means the remote end was not sending any audio stream, or the audio 
stream was not received by Asterisk. The problem may have many different 
reasons, but often it is a network-related issue.

[asterisk-users] 183 Session in Progress. Disconnecting channel for lack of RTP activity

Yes, this means the remote end was not sending any audio stream.
But it shouldn't.
According to [1] before remote end send OK or ACK there is one way SDP, 
no any audio stream.
PJSIP channel (option rtp_timeout) does not take this one.

Isn't it a mistake? What could be workarounds?
