you can record the inbound call audio using yatebts? using wireshark/tcpdump in gsmtap interface it is possible to extract the inbound call audio? i can do this in wireshark using sip for outbound calls (rtp/stream analysis). but it is possible in inbound calls without use sip or iax? yatebts dont have any documenation about calls audio details and how to extract this from .cap capture files.
