I have an OS7200 PBX system, i connected a GSM terminal to trunk port to act as a co-line for my office but it shows no clip info when the gsm number is called. so i tried it on an OS7030 and did all the configuration that is MMC 414 to set cli trunk on, and mmc 110 to set ringing display on line 1 to CLI number first. is there any other thing i can do to get my caller ID showing?
