I have previously setup a few Asterisk systems but with plain POTS phone lines and a card or FXO device.
Now I need to do it for an E1 with 15 lines and I am not sure how to proceed.
These are the specs for the E1 line, translated form Spanish as best as possible:
E1 Type = PRI-ISDN
Number of Channels= 15 channels
Encoding Type= HDB3 (High Density Bipolar of order 3 code)
Impendace = 75 Ohm
clock Type= Slave
dial type: Overlap
all 7 number digits delivered to the customers pbx
I need to select a commercial Appliance and anything else required as well as to know how to set it up for the E1 lines to be used by the ip phones and softphones.
We think we would have no more than 15 outside calls (obviously) simultaneously and about 10 internal calls at the same time.
Any help would be welcome.
You would need to configure DAHDI in a similar way to an FXO card, you would just have a span instead of separate ports. If you post the make and model of your card I could show you a link to the installation guide.
I don’t have any card nor appliance yet. I am also looking for recommendations.
I should add that I want to use the freepbx option specially because the suitecrm plugin that is has.
Maybe Sangoma Appliance and gateway and whatever else I need.
If you don’t have any card yet, you can search the internet for DAHDI E1 configuration, it will show how to configure a PRI span, you would only need to adjust it to your specific card and service.
You can take a look on this link for general information. This is an example from Digium for a E1 ISDN PRI service
A PBXact appliance with a E1 card would be a really good idea, especially since you get some support time with the new device. You could get plenty of assistance from Sangoma and get it all set up and going. Sounds like money well spent to me.
Call and talk to Sales. I’m sure they’ll fall all over themselves to get you squared away.
