i have a problem using different Snom phones (300/320/820/821) with Freeswitch and TLS in a internet-wide setup (phones being registered via internet at a FS w/ public IP). Sometimes (25-50% of cases) the first try to call someone (internal) won't go through. Logs from phone, Freeswitch and ssldump show that the phone sends an INVITE, the FS asks for more credentials (digest auth b/c phone IP not in ACL), the phone answers with an INVITE w/ more auth credentials -- and this second INVITE package is not received by the FS. It does arrive at the server though, as verified by ssldump. Interestingly, if one presses "Cancel" on the phone, a new TCP/SSL connection is created, apparently the old one died -- see logs from phone, FS, and ssldump below. Also, Snom 820/821 show the registrar as not registered after such an action (presumably b/c original SSL connection is dead).
Has anybody encountered this behaviour and can verify it? Are there any ideas what causes the problem here (FS, OpenSSL, phone?) and if there is any remedy for it? I was planning on using FS as a production phone system w/ encrypted signalling and audio using Snom phones. I can't do that right now b/c of the abovementioned problem, and i have not yet found a solution.
Any help is greatly appreciated.
Logs: phone, FS, ssldump, please also see annotation enclosed in "--- ... ---"
