Sangoma PRI/Freetdm issue: LOSE_RACE error on first call after FS startup
Hi All, I recently upgraded my box to Ubuntu 12.04 LTS and re-installed FS from latest git. I'm using a Sangoma A108DE card, interfacing with FS with freetdm. Since upgrade, I'm getting a weird behavior: whenever I first start up freeswitch, the *first call* I make to any of my PRI lines does not go through. The error is pasted below. Subsequent calls go through fine, without the error. So this problem only occurs anytime I have to restart FS; I have to call each of the lines manually to get each of them to "wake up". Judging by the error, my first thought is that this is a Sangoma/FreeTDM/Wanpipe driver issue. Can a real expert weigh in? Happy to provide more logs/output. Thanks!

It would seem we receive a disconnect just after the setup message. In order to determine if the disconnect really comes from the network, we need protocol traces. Try enabling Q.931 and Q.921 traces just after you restart freeswitch. fscli> ftdm sangoma_isdn trace q921 <freetdm-span-name> fscli> ftdm sangoma_isdn trace q931 <freetdm-span-name> The <freetdm-span-name> argument is the span name you configured in freetdm.conf.xml Then also enable some pcap traces at the kernel driver level. wanpipemon -i w1g1 -pcap -pcap_file w1g1.pcap -prot ISDN -full -systime -c trd This assumes your span is the first one (w1g1), adjust as necessary. Start all the traces just after you started FreeSWITCH. Then place a single call in one of your lines (the one you report always fail), then wait a few seconds, and place the second call that should succeed. Finally stop the traces and send them to techdesk@sangoma.com with your description of the problem. Tell them you already talked to me on the FreeSWITCH mailing lists.
