Resource unavailable, call rejected

Hi,

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

Nortel pbx-->Cisco3845voiceh323gateway-->voip

Thanks in advance

Re: Resource unavailable, call rejected

You might be running out of DSP's. Check the number of PVDM's in the Gateway.

Cause i = 0x82AF

82 - From the public network near the local user (local telco switch).

AF - Resources unavailable, unspecified. The requested channel or service is unavailable

for an unknown reason. This can be a temporary problem.
