asterisk list and community,
I have a problem in how our telefon switch (Siemens HiCOM)
“talks” with my new configured Asterisk server (V.11.18.0)
without my Asterisks server in the middle….
<--> Siemens HiCOM <-ISDN-> NTBA <-...-> PBX Telekom
A phone connected to the switch requests an “Outgoing” line by dialing “0”. The party is connected via ISDN to the carrier (deutsche Telekom) where the party preceeds to dial numbers… and the call is connected….
What I can see while I am dialing is that with every digit I press it is being displayed on my phone.
Further more, these digits are being processed by the carrier. The call goes through, rings, immediately on completion on the number or is rejected if busy.
WITH my Asterisks server in the middle of the exchange…
A phone connected to the switch requests an “Outgoing” line by dialing “0”. –> Asterisks recieves incoming call on “s”. The dialed digits are collected. The dial plan is executed accordingly but the “caller” recieves no more information about the dialed number. The number is not placed in the “dialed” numbers simple functions like
“redial” do not work anymore.
Does anybody know what I am doing wrong here. Is there a way to teach asterisk to behave exactly as if it were the PBX (deutsche Telekom).
So, as to say, act in a way that NO ONE will rightly know the differance between having asterisk taking over the function of the ISDN PBX.
What do I need? A better dial plan to somehow better simulate the way the switch normaly behaves?
Is hardware the problem?
My ISDN card in the server is:
“QuadBRI ISDN Digium Wildcard b410P”
Most everything else functionly works. incoming and outgoing calls from and to ISDN, VoIP and other equipment work fine.
Just that the phones and switch don’t recieve the “collected”
number sequence the was dialed.
Any help or ideas anyone might have would be greatly appreciated.
