Hi.
I can't receive DTMF codes from LTE mobile network to asterisk. I try different settings but no luck.
My old GSM gateway GWM400 work good with the same asterisk.
I have try DTMF Hardware Detect Flag On and DTMF Software Detect Flag On with different settings, but result the same.
I record test call by tcpdump and have listen codes inband and no SIP or rtp packets.
