Problem : as soon as I dial a number,number just vanishes from the phone.
I looked at cisco CDR messages::: DisconnectCause 15 , DisconnectText call rejected (21)
Debug isdn gives::: Resource unavailable..Why?
*Mar 2 12:30:35.838: ISDN Se0/2/1:15 **ERROR**: cdapi_process_connect_resp: cdapi sez to reject the call (appl rejected?)
*Mar 2 12:30:35.838: ISDN Se0/2/1:15 Q931: TX -> RELEASE_COMP pd = 8 callref = 0x9100
Cause i = 0x82AF - Resource unavailable, unspecified
Numbers I was dialing was '8700276161
Note, this happens when call volume is high.the cpu processor util was normal.
Set up is like this
Thanks in advance
