I've got a rather strange callerid problem and don't know how to debug it. I've got two X100P cards installed in a RH9 box and both are connected to individual pstn pots lines. Both are equipped with callerid and both display callerid info on regular analog phones (verified 100%). Incoming and outgoing calls are handled just fine. When an incoming call arrives on one X100P card, * rings a defined extension and the callerid "is" displayed on the 7960 phone. However, when an incoming call arrives on the second X100P card, * rings the defined extension, but the callerid is always "asterisk" on the 7960 phone. This was working fine a few days ago and I'm not sure what happened to cause * to display "asterisk" instead of the actual callerid. As mentioned above, the pstn line "is" providing the callerid info, but I don't know if * is not picking it up or simply substituting "asterisk" on the 7960 display for some reason. Is there a way to debug callerid info within * to help identify the root cause of the problem? My zapata.conf file for both pots lines is: ; Zapata telephony interface ; Configuration file [channels] language=en context=inbound-home switchtype=national signalling=fxs_ks usecallerid=yes hidecallerid=no callwaiting=yes callwaitingcallerid=yes threewaycalling=yes echocancel=yes echocancelwhenbridged=yes rxgain=0.0 txgain=0.0 pickupgroup=1 immediate=no callprogress=no musiconhold=default channel => 1 context=inbound-bus switchtype=national signalling=fxs_ks usecallerid=yes hidecallerid=no callwaiting=yes callwaitingcallerid=yes threewaycalling=yes echocancel=yes echocancelwhenbridged=yes callerid=asreceived rxgain=0.0 txgain=0.0 pickupgroup=1 immediate=no callprogress=no musiconhold=default channel => 2 Anyone see a problem or know of a way to diagose the problem within asterisk? (The "inbound-home" context is working, the "inbound-bus" is the X100P not providing the appropriate callerid.) Rich
