I am new and I want to say hello to everybody!
I am coming with a perhaps “newbie” question. A friend asked me to build up a Asterisk system for his small European company. 2 mgr. seats, 6 employees, 2 faxes, 1 ISDN modem and some additional desk phones. So in sum ~15 extensions. The current setup is a “traditional” PBX connected with 4xBRI EuroISDN.
Which is the best BRI EuroISDN interface card for a Asterisk machine?
All 6 people are using DECT phones and there are just a few desk phones. So they want to keep their mobility, which means that they want to keep their phones. To keep these phones I will need a FXS gateway or I have to replace all phones against wireless IP Phones (which is much to expensive).
I informed me and saw that there are some possiblities:
- FXS Interface cards
- ATA with 2 ports, 4 ports, 8 ports?
- ATA with 4 ports
- Media Gateway with T1 or E1 interconnection to a ISDN interface card.
What is the best solution? Which is the cheapest one? What is the best hardware for the FXS gateway?
As mentioned above they are using an ISDN modem which gives a external partner service connectivity for some machines.
How do I connect this one to the Asterisk server?
They asked me for a GSM gateway. I saw that the boxes begin at 2 lines and can connect via ISDN BRI or FXS/FXO.
Do you have recommendations? Do I need any additional hardware except the GSM gateway itself?
I would really appreciate your help,
and thanks for your help in advance,
