Grandstream HT 488

[cjammer]

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.
