Logging ISDN events with dahdi and freeswitch

Question

I am using freeswitch with dahdi. I have a need to log the ISDN events for all the calls that land on the PBX (freeswitch). Is there any way to do this?. I thank you kindly for your help.

Thanks in advance.

Answer 1

Change to your dahdi source directory and issue:

apt-get install libpcap-dev || yum install libpcap-devel
sed 's/^.*\(\#define\s\+CONFIG_DAHDI_MIRROR\).*$/\1/' linux/include/dahdi/dahdi_config.h
make clean
make all
make install
cd tools
make dahdi_pcap

If compiled without errors you now have a tool called dahdi_pcap and you can capture the signaling to a pcap file and analyze it using wireshark. usage example:

./dahdi_pcap -p lapd -c 1 -f isdn.pcap
