This one's probably for MikeJ... I am testing out the PRI on OpenZAP. My carrier doesn't support DMS100 so I'm using an Asterisk box to act as my telco. I'm set up on Asterisk with pri_net signaling in Zapata.conf, using the 24th channel as the D channel. I'm pretty sure that the D channels are communicating because I'm getting an error on the actual data sent. Here's what I see when I start up FS: 2007-11-02 22:39:46 [DEBUG] zap_isdn.c:223 zap_isdn_921_23() READ 13 ------------------------------------------------------------------------ -------- [08 02 00 00 46 18 03 a9 83 82 79 01 80] 2007-11-02 22:39:46 [DEBUG] zap_isdn.c:227 zap_isdn_921_23() 931 parse error [-3012] [Q931E_INVALID_CRV] If I read my Q931 specs properly, the data being sent over in this case is a RESTART (the 46 in 5th octet). Question: does the parse error indicate a setup issue or do you think possibly that Asterisk isn't necessarily a good way to emulate a telco PRI circuit? On a DMS100, what would the proper RESTART string look like coming from telco? Thanks, MC
