I'm trying to configure a QSIG T1 PRI on a 3825 running 12.4(8) but the link is not establishing. I have the router configured to be the network side but it
appears to be ignoring that command. Here is the output from "debug isdn
*Jun 26 22:38:53.242: ISDN Se0/0/0:23 Q921: L2_EstablishDataLink: sending SABME
*Jun 26 22:38:53.242: ISDN Se0/0/0:23 Q921: Net TX -> SABMEp sapi=0 tei=0
*Jun 26 22:38:54.242: ISDN Se0/0/0:23 Q921: Net TX -> SABMEp sapi=0 tei=0
Isn't that backwards? According to the CiscoPress book Troubleshooting
Cisco IP Telephony, the SABME frames should be incoming from the user side if
the router is configured as the network side. Instead, the router still appears
to be sending the SABME, which makes me think that the link isn't coming
up because both sides are acting as the user side. Our PBX guru says that the errors she's seeing indicate that the PBX is receiving frames that it should not be receiving.
From that debug output, can you tell me if the router is actually behaving as
the user side even though I have "isdn protocol-emulation network"
I checked the Bug Toolkit and I don't see any bugs related to this.
