[Asterisk-Users] ANI & DNIS sent to analog FXs Port Possible
Good Day list, Need assistance determining the best place to read up on whether Asterisk can help me out. I have a situation where I need to do the following <PRI from Telco> ------- <Analog Channel Bank>------------<Proprietary Box> | | | | | | <PRI Port 1 of Digium Quad T1> <PRI Port 2 of Digium Quad T1> | | | | | | ---------><Asterisk Box with Quad T1>------------------ | | | ------------------------------------------------------- | | | | | | | | ext. 100 ext. 101 ext 102 ext 103 A standard T1 or PRI service are both digital and require to be converted to Analog to work onto the Proprietary System, as the need to receive analog with the DNIS and ANI information is important a product must be used which will allow for this. <YUCK> The Lucent G3, Intertel and Comdial switches are capable.</YUCK> I want to put Asterisk in here All PBX switches must have the capability of passing the DNIS (DID) and ANI information onto an FSX analog port, please check your current switch or talk to your provider. My question is : "Am I correct in thinking that I can have asterisk answer the incoming call from telco on the PRI, Grab the ANI/DNIS Information and then route it to a channel back via a second PRI Port and have the channel bank pass the ANI/DNIS of the original caller oout to the proprietary box in an analog fashion?" My understanding is that the Proprietary box does its magic and then would need to transfer the call back to a Specific user on the PBX via flash hook transfer. If I am on the right track can anyone point me in direction of channel backs that will accept Digital "PRI/T1" connection on the front and "Analog connection on the back"? Is there a better way to do this? Maybe a Sip Analog Gateway? Anyways, thanks for your help in sorting through this with me. ~ron

Asterisk (at least stable v1.06) does not seem to support DNIS. - DNIS and $EXTEN are not the same thing. We have discovered this recently where we had a block of telephone numbers in Adelaide diverted to a second block of numbers in Perth. $EXTEN in asterisk showed the local Perth number rather than the Adelaide number originally dialled by the caller. $RDNIS also failed to show the original Adelaide dialled number. The setup we have is where the E1 from the telco connects to span 1 on the TE405 and then span 2 connects to a Dialogic E1 board. If we dial the call through from span 1 to span 2 without answering it, the DNIS variable on the dialogic shows the correct DNIS number - ie the Adelaide one. So to me it demonstrates that at keast zaptel or libpri is aware of the DNIS, it just doesn't seem to make it available to Asterisk.
