This is for a school to use for notification to all classrooms. VOIP is on it’s own VLAN with about 40 phones (GXP1625). All the phones would ring and auto answer but no one can hear me.
I’ve used *81XXXX (*811212) paging group is 1212. Same thing if i dial 1212#. I created another group 1234 with only 2 extensions which works fine. I don’t want to use the intercom because of the noise coming from other end.
UCM6102 Firmware 22.214.171.124
Could it be firmware? I read 126.96.36.199 compared to 188.8.131.52 there’s a delay on ringing the phones.
Could it be because of VLAN use? I don’t want to use multicast. I need it to go thru the UCM.
