Call to peer '101' rejected due to usage limit of 1

Всем привет. Настроил на * очередь для входящих звонков. И теперь периодически получаю вот такие сообщения в логах:

han_sip.c: Call to peer '101' rejected due to usage limit of 1
han_sip.c: Call to peer '106' rejected due to usage limit of 1
han_sip.c: Call to peer '108' rejected due to usage limit of 1

call-limit на каждого SIP оператора действительно =1. Но насколько я понимаю, звонок должен висеть в очереди до тех пор, пока кто-то из операторов не освободится или абонент сам не повести трубку. Из за чего происходит попытка позвонить занятому оператору? Мои настройки:
