[Asterisk-Users] Help with E1 configuration

[Scott Stingel]

zaptel.conf looks good - you may require a ",crc4" at the end of the span
line, depending on your provider.  I have "loadzone=us" in mine as well.
Change appropriately for yours.

zapata.conf also looks good.  I would also add the following, before the
channel declaration:

immediate=no
pridialplan=unknown
usecallerid=yes

Setting immediate=no allows your calls to be answered and routed according
to the DID entries you make in your extensions.conf file (the "dialplan").
Setting it to yes would cause the "s" extension to be used instead.

So you need entries in the dialplan for each DID, under the context
"[default]" which you have defined in zapata.  That will take care of
inbound calls.

Outbound calls:  Since you've defined group 1 as including all channels of
your PRI, you can use the Dial command and use a "g1" instead of a specific
Zap channel, to allow asterisk to choose an available channel.

All of this is covered on the Wiki:

Good luck with your project!

Subject: [Asterisk-Users] Help with E1 configuration

Hi,

  I currently have a E100P card installed on my machine and the E1
subscription will be activated pretty soon. However, I have no idea how to
configure asterisk to make inbound and outbound call using the E1. 
Especially for extensions.conf. Below is the configuration I used for
zaptel.conf and zapata.conf. Is it possible if someone can verify if the
configuration for zaptel and zapata is correct?

   zaptel.conf
  -----------
  span=1,1,0,ccs,hdb3
  bchan=1-15,17-31
  dchan=16

  zapata.conf
  -----------
   switchtype=euroisdn
   signalling=pri_cpe
   group=1
   context=default
   channel=1-15,17-31


  I have 1 block of 10 DID numbers that will be subscribed together with E1.

I am not able to find any sample for the extensions.conf to do inbound and
outbound call. Is it possible for someone could post a sample of how the
configuration would look like. Any setting missing for callerid support?

  PS: I already have an existing asterisk system running on analog ports. 
This is just an upgrade.

  Thanks in advanced.

  Regards,
  Chin
