Anyone with a tip?
Have a look at this document:
On the bottom of page four it says:
Cisco IOS currently only supports layer 2/3 network side operation with QSIG, NET3 and NI ISDN
Since you are using NET3, it looks like the Cisco card won't provide clocking (Layer 1) - can you have your Alcatel provide this? Or use a different ISDN switch type setting?
First thx for the fast help.
I looked the document but in the document isnt talking anything about layer1 :(.
the card from the alcatel must be in slave mode because is the same card that is connected to the public PBX.
I have the same problem on c3725, c3640, c2600xm models. Older versions of IOS worked fine on model c2600xm (12-2-16 or 17 IPPlusIPsecDES). We tried to change the gender (in a lab) and the clock timing looked stable.
