c2600 bearer cap issue

Hi all!

On a 2651XM with 2 BRI port, we recognize a strange problem. Direct inward dialing is ok, let's say on phone 2105. If I redirect a phone in the PSTN to 2105 (redirected by provider network), the provider network sends a additional information with the call, so the call will fail with the ISDN debug message "ISDN ERROR unsupported bearer cap".

Does anybody know about that problem?

Thanks, Andy

Re: c2600 bearer cap issue

We need to see what are that additional information which comes with the isdn SETUP message for a forwarded call which is not received in the regualr dialin call.

So pl. enable the "debug isdn q931" and make a call directly from pstn to that 2105 AND also capture the same for a call forwarded to that 2105. Post both the isdn debug here so that we can compare.

Re: c2600 bearer cap issue

Thanks for the reply. Here a quick describtion of th e situation:

First Call to phone "22" from "0794060041" (calling id is not visible because it is anonymous!) is ok. Then I redirect the phone "0794060041" to "22" and call it from another phone, the call fails. Below you can find thew debuging of this behaviour:
