Cause i = 0x80AC - Requested circuit/channel not available on Incoming Calls

Hello,

I am facing problems with incoming calls on a MGCP PRI Gateway. Some of the incoming calls get disconnected with cause code: Cause i = 0x80AC -

Requested circuit/channel not available - Destination address is non-ISDN

I noticed that this happens only on  one specific port/channel.

Cause i = 0x80AC - Requested circuit/channel not available on In

Do you by any chance have a fractional T1?

Can you try to bounce the T1?

Is it always with the port?

Try No Mgcp/MGCP on this guy.

ANy way you can forward the sh run, or at least the part with the mgcp/ccm-manager configuration?

Please Kudos/rate if this help!

Cause i = 0x80AC - Requested circuit/channel not available on In

Probably is caused by the way the ISDN B- channels are being address and probably in which order

reason code:

80AC: The remote equipment cannot provide the channel that the user requests, due to an unknown reason. This problem is usually temporary.

as per:

http://www.cisco.com/en/US/partner/tech/tk801/tk379/technologies_tech_note09186a008012e95f.shtml

Can you check the channel selection on your MGCP Gatways PRI interface and see if it is bottom up, top down, alter it and test again.

Do you notice this behaviour only on inbound calls or outbound calls as well.

You can test this in oubound call by changing the order in the gateway and check if the error seems to follow only with a particular channel.

You won't be able to select the channel for inbound call as it is selected by the provider.

If you notice issue only on a particulat channel..then you can busy out that channel and check if anyother channels are affected as well.

I have seen this issue before where bouncing the controller will give it a temproary fix.

Rate if it helps

Thanks

I manage to find what was the problem. The problem was I do not have enough PVDM on the router and from the last E1 the first 10 channels work k and the rest cannot receive calls.

Have a nice day
