How did you configure POTS with VoIP? With Asterisk? I'm trying to do outcalls with Asterisk(13) and ISDN. I have no success. I bought some Netcologne-Cards, got them working in TE and NT mode, have configured dialplans and so on. My isdn-phones are working, but I can't call out with a isdn-ta either an modem thru my isdn-telephone system. Because I got german-telekom, it should be working. German-Telekom does allow rfc4040 for g711-raw. But the whole stuff does not work.
