We have a Siemens HiPath PBX here at work. People call in and select from a range of options.
After hours, one of those options gets diverted to a mobile phone.
The problem is, the person answering the mobile phone only sees the caller ID of the main line here at work - they don't see the caller ID of the actual caller.
I understand that effectively the PBX is making a call to the cellphone and that's why we see that main number, but is there no way to 'transmit' or forward on the caller ID of the original caller?
I asked the company who installed it and they told me no....but somehow I don't believe them. I need confirmation from a technically minded community such as this.
Please help if you can.
