<div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">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". </div>

</div><div class="gmail_quote">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 <a href="mailto:techdesk@sangoma.com">techdesk@sangoma.com</a> with your description of the problem. Tell them you already talked to me on the FreeSWITCH mailing lists.</div>
