[Freeswitch-users] mod_callcenter related questions

Hi all, I'm playing around with mod_callcenter and hitting some questions: * what means position and level in tier configuration ? Is it only related to queue parameter 'strategy' ? * having more than one agent in a queue logged in only the first agents phone rings for tier_rule_wait_seconds but the call is not directed to the next tier/agent logged in to the queue * is it possible to configure overflow destinations means if a call isn't answered in a certain queue it's overflowing to another queue ? Any help would be nice. Thanks in advance and best regards Stefan
