R24FXX-EC Modular Trunk Question

Alan,

I'll give you a couple of things to look at. Hang on because this is a whirlwind tour. (even though the post is a small novel :-) I assume you have your card setup in /etc/zaptel.conf for the proper signalling so we'll just skip over that.

The money section is in /etc/asterisk/zapata.conf. You can get there through the config edit selection on the asterisk menu in Trixbox. If you followed the Rhino instructions, the section you need will actually be in zapata-auto.conf. Look for something like this:

; Span 3: Rhino RCB8FXX/1 "Rhino RCB8FXX/1"
;;; line="49 FXO/1/0"
signalling=fxs_ks
callerid=asreceived
group=3
context=from-zaptel
channel => 49
context=default

The two important parameters for your setup are the 'group' and 'context'. It is important to note that the lines before 'channel => ' are the only ones that count. The channel parameter makes the setting stick to the assigned channel.

In your case, with 6 lines that you want to divide in half, you will want to put the first three channels all in one group (just assign all three the same group number) and the second three in a different group. (maybe 0 and 1) This is how you will access them in trunk config. More on that in a bit.

The context line is important as well because you have a choice to make. If you want to handle just the two groups when you setup inbound routing then you should set the context as 'from-pstn'. If you want to handle each line as its own DID, then you must set the context to 'from-zaptel'. I'm guessing that in your case that you probably have hunt setup on the lines so inbound calls hit lines in ascending order (1, 2, 3) and you want outbound calls to go in descending order. If so, you probably want to treat all three as 1 group and assign the context as 'from-pstn'.

Now, in freePBX you need to setup the trunks and the inbound/outbound routes. Again, I'm assuming that you want all the phones in company 'A' to ring with an inbound call in group 0 and all the phones in company 'B' to ring on an inbound to group 1. In this case you need to setup two Zap trunks. The important part of the trunk setup is getting the Zap identifier correct. This matches the trunk to the groups that you defined in Zapata.conf. So, assuming you use groups 0 and 1, you would setup two trunks with the zap identifier 'g0' and 'g1' respectively. Note that the "g" means group but it also defines the dial-out channel selection order. A lower-case g means dial lines in descending channel order (what you probably want) while an upper-case G means dial them in ascending order. (I could have this backwards... I'm going from memory).

For your inbound routes you will probably want to use the Zap DID feature in freePBX. Assign a DID number to each channel number in zapata.conf and then you can use the DIDs to build inbound routes. So you may take the channels in group 0 and assign them DID 1001, 1002, 1003 and then repeat for the other three but set them to 2001, 2002, 2003. In this way you can create an inbound route for each DID (or use pattern matching) to selectively route the calls. I would create two inbound routes and set the DID to '100[1-3]' and '200[1-3]' respectively. Set the destination for each to a seperate ring group for each company that includes only their phones. You can also include the receptionists phone into both ring groups and that phone will always ring.

That ought to be enough to get you close.

Apparently I'm blind, and I missed a big section for assigning DIDs to channels. So I have that all straight. What I need to know how is how to get some sort of identifier to be passed on with the caller ID so that the receptionist knows what trunk the call came from. And I've still made almost no progress getting outbound to work, all I get is all circuits are busy or call cannot be completed as dialed. Thanks!

Hi evereybody, im just new on this, so any help from you will be great. I installed trixbox 2.6.1 , i 've a multitech voip gateway (8 fxo/fxs) and i want use it with all fxo to pstn. The point is i made sip accounts. my outbound and inbound calls are ok, i configured an ivr, and the basic is fine. But i want to distinguish the extensions for the offices , i mean, i want to give to the main office an outbound route (for 2 fxo channel), and only one to the others offices. So , how i create the system to make that the extension range (100-1xx) can use one outbound route, and the extension range (200-2xx) only can use its unique outbound route? (something like "this two phone number are for this office and this is for this one , nobody who call from "this" phone number can reach "that" extension range but they can reach only this.)
I start with the outbound firts, it would be nice for both (the outgoing and inbound).
any idea will be just great, thanks, landylan
