FreeSWITCH is fairly old (2012-05-30), though I haven't seen many fax-related changes lately.<br>I'd love to try git HEAD but it's fairly hard given tat new Debian packages complately change filesystem structure.<br>
The Cisco uses User-Agent Cisco-SIPGateway/IOS-12.x, no idea what model it is.<br><br>Hope there is any way to debug this without upgrading to git HEAD.<br><br><div class="gmail_quote">2012/10/18 Brian West <span dir="ltr"><<a href="mailto:brian@freeswitch.org" target="_blank">brian@freeswitch.org</a>></span><br>

I do have full SIP/RTP dump of such a call if it is of any interest. It<br>seems to be a peculiar interoperability issue, as this setup is used as a<br>email2fax/fax2email gateway and it works quite well.<br><br>Could anybody recommend any steps I could try to debug/fix the issue?<br>
