Hey all, please I have a cisco 3640 with 2 T1 voice ports. I use this box for my VoiP calling card service. The cisco is connected to a TDM softswitch that do my billing. Now I am changing to a no TDM software billing:
1. how can I connect the 2 T1 voip together without the TDM, also can I use the same connection I was using before. Finally, how can the cisco 3640 and billing software communicate, that is billing the customers.
