Example 1
Debug: DEBUG ISDN EVENT
BRI0: ISDN Event: incoming ces value = 1
BRI0: received HOST_TERM_REGISTER_NACK - invalid EID/SPID or TEI not
assigned
Cause i = 0x8082 - No route to specified network

Indication:
Usually a SPID problem. To verify that TEI is assigned, try show isdn status. Layer 2 information will tell if TEI is
assigned.
Suggestions:
1. Check the configuration to see if the SPIDs are configured correctly.
2. Have your service provider verify the SPIDs, and if necessary have them track the SPIDs.

Debug: DEBUG ISDN Q931
BRI0: Dialing cause: BRI0: ip PERMIT

Signal i = 0x3F..
Indication:
Remote router does not answer call.
Suggestions:

Verify the telephone number and SPIDs.
