[Asterisk-Users] Problems splicing Asterisk with a TE405P between Arcor E1 PRI and Ericsson Business Phone 250

[Frank Sautter]

hi,

i'm having problems getting asterisk spliced between an E1 PRI (german 
Telco Arcor) and an Ericsson Business Phone 250 digital PBX.
The Asterisk Server has a TE405P with it's port 1 connected to the E1 
PRI provided by our telecommunications provider Arcor and port 2 
connected to the E1 PRI of our Ericsson BP250.

the setup before:
Arcor TelCo PRI(E1) <------------------------> Ericsson BP250 PRI(E1)

the setup desired with asterisk spliced in:
Arcor TelCo PRI(E1) <----> P1 asterisk P2<---> Ericsson BP250 PRI(E1)

receiving and making calls between asterisk and the outside (arcor) 
works so far (not entirely tested yet), but making calls from the 
ericsson PBX to the asterisk server and routing them through to the 
arcor PRI is not working.

the message i get when making a call from the ericsson pbx is:

"Extension '' in context 'pri-ericsson' from '123498765' does not exist"

obviously the ericsson pbx is not sending the dialled number on the pri 
  (but the calling number is set correctly)

as there is very limited time for me to play around with the parameters 
in the asterisk config files (as the ericsson is in production use), i 
hope the community can help me.

i think zaptel.conf is OK, as the LEDs are all green and the 
communication between the all devices is working.

do i have to make changes on the ericsson PBX or in the zapata.conf?

regards
   frank


here are some fragments of my config files:
