Intermittent one-way audio across CUBE

Currently Being Moderated
one way audio before press any buttonHi Expert and Every Member,


My UC System include  CUCM 8.6 , 1 Voice Gateway 3925 with CUBE, 300 Agent IP Phone 7942 .We can do outbound call very well. Unfortunately, when customer from PSTN do inbound call to ip phone(agents), they sometimes get one way audio call that means customer can hear ip phone's voice but Ip phones can not hear customer voice. But if customer press any button on his phone(one or few times) their are two way audio which mean is the ip phone (agent) can hear the customer voice??  This call is happen very intermittent about 10 inbound call success i get 1 one way audio inbound call. I try to do many ways to

- Check IP Routing, i can ping everything.


- All IP Phone, VoiceGateway on primary CUCM

my toplog show below:

Re: Intermittent one-way audio across CUBE

Plus the config, please share the output of "sh call active voice su" and indicate the calling\called number. In your CUCM what is the codec settings for the regions of CUBE/SCCP phone.

Intermittent one-way audio across CUBE

Please share proper full config. You are sharing part of it which isn't useful to look properly. We are interested in full config not only dial-peers.

Plus we need to know what are the codec settings on your CUCM, any MTP or XCODER configured, etc.
