Using YateBTS in GSM roaming and GSM dataroam working modes traffic can be captured/analized with Wireshark.

  • Enable GSMTAP.GSM capture from the Yate rmanager (telnet 0 5037)
    • mbts config TAP Control.GSMTAP.GSM on (GSMTAP.GSM will capture SIP and RTP packages)
  • Enable GSMTAP.GPRS capture from the Yate rmanager
    • mbts config TAP Control.GSMTAP.GPRS on (GSMTAP.GPRS will capture GTP-C and GTP-U packages)
  • To check if GSMTAP is enabled type mbts config TAP in Yate rmanager.
yate-sdr@ybts-UNCONFIG> mbts config TAP 
Control.GSMTAP.GPRS on
Control.GSMTAP.GSM on
Control.GSMTAP.TargetIP 127.0.0.1     [default]
yate-sdr@ybts-UNCONFIG> 
  • To capture traffic use tcpdump: tcpdump -i any udp port 4729 -w GSMTAP-yatebts.pcap
  • Or Wireshark, already installed on the LatKit/SatSite by adding a custom filter: udp port 4729.
