Hi, Now I'm using Asterisk version 1.6.22. I use two server cluster with load balancing mode. My problem is: If one phone from a pickup group is moved to another server, he can not take over the group call and someone call he the other pickup group members can not take over the his call. Slowly I would like to upgrade the Asterisk, the current new versions handle such calls (1.8.x or 10.x)? Sorry for my bad English. Regards, Zolikusz
