Asterisk configuration for ISDN & IP

The purpose is to configure Asterisk to handle incoming calls from two phone lines (ringing simultaneously), answering only one line, and bringing that call into the dial plan. Furthermore, the configuration most integrate with two SIP external lines for dial up. The current problem with the incoming calls is that the two phone lines are on an ISDN box, thus ringing simultaneously. They are connected to ports on a TDM400, thus making Asterisk believe two separate lines are ringing simultanously, causing it to answer both lines. However, when the first line is answered, Asterisk does not detect that the second line is not relevant any more. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
