| Hicom 150 Analog extension line does not ring
Hello,
We have just reload Hicom 150E OfficeCom PABX. Almost everything works, except that the analog extension lines won't ring. It simply silent. However, if receiver picks up the phone, the conversation will begin. (Silent ring feature?)
I searched menu in Optiset E Memory but can't find menu related to this problem.
The PABX has one TLA8 and two 16SLAs. I tried connect analog at motherboard and both 16SLA. They're all silent ring.
Can anyone tell me how to fix it? Thanks. |
