[asterisk-users] Bridging of PRI calls
Hello ! I 've some questions how bridging of ISDN calls is done. Assume an asterisk system with a TE405 card equipped. (PRI1 - PRI4) An incoming ISDN call on PRI1 is transfered back to PRI3. Unless there is DTMF detection or other things involved, the bridging is done without Asterisk. Does this card have a some sort of cross connection ? Does the PCM leave the card ? Or is there some DMA magic in- volved ? Assume an asterisk system with two TE405 cards equipped. An incoming ISDN call is transfered back to the second TE405 card. Does this card have a seperate bus like H.100 ? How is the bridging done in this scenario ? I could not find useful information on the Product sheet, sorry.
