I have a Cisco 2620 with IOS 12.0(7)XK1 with a NM-2W, 2 WIC-1B-U ISDN interfaces and the serial 0/0
is active on a frame-relay network. The ISDN blades are to serve as a backup in the event of a frame-relay outage. Initially, I had the 2 ISDN blades in the NM-2W. I was unsuccessful in receiving/placing any ISDN calls. I moved one ISDN WIC to 0/0 (off of the NM-2W) and was unsuccessful in receiving/placing
an ISDN call. I am now down to one ISDN WIC in the router (0/0) and still cannot receive/place an ISDN
call. Sho ISDN Stat returns:
Global ISDN Switchtype = basic-ni
ISDN BRI0/0 interface
dsl 0, interface ISDN Switchtype = basic-ni
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 72, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
TEI 72, ces = 1, state = 8(established)
spid1 configured, no LDN, spid1 sent, spid1 valid
Endpoint ID Info: epsf = 0, usid = 1, tid = 1
TEI Not Assigned, ces = 2, state = 3(await establishment)
spid2 configured, no LDN, spid2 NOT sent, spid2 NOT valid
Layer 3 Status:
0 Active Layer 3 Call(s)
Activated dsl 0 CCBs = 1
CCB:callid=0, sapi=0, ces=2, B-chan=0, calltype=INTERNAL
The Free Channel Mask: 0x80000003
Total Allocated ISDN CCBs = 1
The spid 2 not sent/not valid MAY be a caveat with the 2620 and IOS 12.0(7) as I have another 2620 with the same config reporting the same issue with SPID2 and it works. In any case, I cannot
receive a call (the remote router is configured DDR), nor can I place a call.
Debug ISDN events reveals the following when trying to place a call:

The Telco has been out twice and both times the circuit tested good. The SPIDS are correct as is the
switch type (basic-ni). The dialer number is also correct.
HELP!
