We have deployed a UCCE 9.0 with CVP 9.0, using CUBES to connect to the outside world.
Because our client would like to use CVP survivability in the future we already enabled inactivity detection as follows:
timer receive-rtcp 4
timer receive-rtp 1200
It turns out these settings have an influence on back office calls (not passing through the CC, i.e. direct inbound calls) as well.
Calls not answered within 20 seconds are cancelled by the CUBE.
According to Cisco TAC this behavior is by design, as the initial INVITE from the provider contains a DSP (early offer), which activates inactivity detection for that call.
I've been reading up a bit on inactivity detection, and I have the impression that it can be activated on specific applications or dial peers, i.o. on the CUBE level. I'm not a big CUBE/gateway expert, so I would appreciate if anyone can confirm this.
Or are there other ways to circumvent this unwanted behavior?
Thanks in advance!
Can you try to Configure "media-inactivity-criteria all" and disable media inactivity detection for calls
that do not require survivability such as calls to voicemail.
Note that RTP / RTCP based media detection may trigger media inactivity event for calls to Voicemail, VXML Gateways, Recording Apps that do not send RTP / RTCP packets when they are idle.
