    After playing with it for months and a lot of reading, I have finally made the HT488 place calls to PSTN from the 3CX PBX and receive calls from PSTN to a 3CX PBX extension. Now I can be happy and move on to other experiments.

    Has anyone else been able to get it to work like this?

    I'm using HT-488 as well. However, I cannot make use it as PSTN gateway for place calls to PSTN from the 3CX PBX. Incoming calls are no problem. May I know how to config HT-488 as PSTN gateway for place calls to PSTN from the 3CX PBX?

    PSTN number: 29070901
    EXT number: 100
    HT-488 internal number: 1000
    Outbound Rule for HT-488 at 3CX PBX: 88 mask: 00rr
    Prefix dail to PSTN at HT-488: 00

    It works on this steps:

    1. off hook EXT 100
    2. dail 1000 (wait for the tone change)
    3. dail 00 (wait for the tone change)
    4. dail 29070901

    Not works at normal step:
    1. off hook EXT 100
    2. Dail 88 29070901

    I have a Couple page Document I typed up on configuring the HT-488.
    I will post it to my website and you can get it from there.

    It is a bit big to post in a forum box.

    I will post the link when I get to it. It may be next week. So dont panic.
