Hello, After trying to upgrade to version 1.6.6 I've found that quite often Freeswitch crashes when a user tries to un-hold a held call. I've already opened FS-8739 a few days ago, but no comment yet. With version 1.6.5 it works ok. Has anyone also noticed it? I tried it with Polycom phone, as this is what I have in my lab. Thanks, __Yehavi:
