Hi all,
I have a Cisco 2901 configured with an E1 PRI and connected to a Siemens hipath 4000 version 2. Incoming calls from the Siemens are delayed in call proceeding about 15 seconds. The Cisco configuration is:
isdn switch-type primary-qsig
isdn voice-call-failure 0
!
controller E1 0/0/0
clock source line primary
pri-group timeslots 1-12,16
!
interface Serial0/0/0:15
description D-channel for ECN-8

You can see the status:

I thought about the wildcard (.T) on dial-peer was cause the issue so when I changed these, the problem still remained the same.
What can be the reason of this?
Can somebody help?
Regards.
