I ran across this when looking up something on span syntax yesterday (from http://www.voip-info.org/wiki/index.php?page=Zaptel.conf+span+syntax): Framing= how to communicate with the hardware at the other end of the line. For T1: Framing is one of *d4* or *esf*. For E1: Framing in one of *cas* or *ccs*. Coding= another parameter of the communication with the other end of line hardware. For T1: coding is one of *ami* or *b8zs* For E1: coding is one of *ami* or *hdb3* (E1 may also need crc4) I have NI-2 PRI service from Telus in Ontario, and my spans are set up as: span=1,1,0,esf,b8zs And my zapata.conf reads: switchtype=national signalling=pri_cpe I don't have rxwink explicitly set to anything. I'm not a digital trunk expert by any means, but I thought the wink/flash/start time settings were used on trunks that don't have a dedicated signaling channel the way PRI does. If you leave it as pri_net, you'll probably see messages to the effect that "I think I'm PRI_NET but so does the other end". -- j.
