Hi there

Are you using full PRI or a fractional one. You might need to check with your Telco also.

I just did a search and found the same exact issue got resolved by Unchecking "Inhibit restarts at PRI initialization" on the CCM gateway configuration page. Reset the GW after the change

Hope this helps

Thanks for your answer, is a full PRI, but in my ver of CUCM, that check box, doesnt exist :(

This is the config if you want to take a look.

Can you try changing the isdn bchan-number-order ascending to descending and see that helps

Hope this helps

 Thanks Ratheesh,

Yes I did and still have the same error :(

[R0g22 · Accepted solution]

Have you talked to your Telco ? The disconnect is being generated by them -

0x82AC >> 82 is an upstream switch or device in the PSTN network

Also, you are sending an internal extension out to your Telco ? Is that right ? Change it to a permitted DID.

Calling Party Number i = 0x0081, '3898'
Plan:Unknown, Type:Unknown

[samaelsaenz]

Thanks Nipun, i will try this, i hope this solve this problem.

Regards,

[samaelsaenz]

Seems the error still show, same error, i do not know what more to do ATM,

Some suggestion?

Regards,

[R0g22]

Did you contact your Telco like I highlighted earlier ?

[samaelsaenz]

Hi and thanks a lot for your anwers, we talk to Telco team and yes, some missconfig, now it works.

Thanks a lot.

[CHI-Voice]
