Our tech team enabled high debug in our Asterisk and we can found that this beeps are an DTMF tone.

In asterisk logs it's possible see this things many times:

We done a wireshark capture to find out what is happening and it's possible see an RTP EVENT see file attached.

Could you please, help us to solve this issue?
