Hello,
I dont normally work with BRI cirucits, so I was wondering if someone can provide some assistance. I have 4 BRI circuits in France and when I dial one of the DIDs I see 2 calls coming in at the same time, debug isdn q931:

Here is my config:
!
interface BRI0/1/0
no ip address
no ip redirects
isdn switch-type basic-net3
isdn overlap-receiving
isdn point-to-point-setup
isdn incoming-voice voice
isdn supp-service name calling
isdn sending-complete
trunk-group Local-BRI 1
!
interface BRI0/1/1
no ip address
no ip redirects
isdn switch-type basic-net3
isdn overlap-receiving
isdn point-to-point-setup
isdn incoming-voice voice
isdn supp-service name calling
isdn sending-complete
trunk-group Local-BRI 2
I tried the following command without any difference as well:
isdn tei-negotiation first-call
Outbound does not work at all. IOS is 15.1.4M4.
Is there something I am missing, any idea what is going on here?

These are my working config in Italy.
BRI Point-to-Point in TE mode, this config required static TEI 0 in Italy:
interface BRI1/0
description from TI
no ip address
isdn switch-type basic-net3
isdn overlap-receiving T302 6000
isdn not-end-to-end 64
isdn point-to-point-setup
isdn incoming-voice voice
isdn static-tei 0
isdn skipsend-idverify
voice-port 1/0
input gain -2
output attenuation 4
no non-linear
no vad
compand-type a-law
playout-delay nominal 160
playout-delay mode fixed
cptone IT
timeouts interdigit 6
bearer-cap Speech
BRI Point-to-Point in NT mode, this config required static TEI 0 in Italy:
interface BRI1/1
description vs PBX
no ip address
isdn switch-type basic-net3
isdn overlap-receiving T302 6000
isdn not-end-to-end 64
isdn protocol-emulate network
isdn layer1-emulate network
isdn incoming-voice voice
isdn send-alerting
isdn negotiate-bchan
isdn sending-complete
isdn static-tei 0
isdn skipsend-idverify
line-power
voice-port 1/1
input gain -2
output attenuation 4
no non-linear
no vad
compand-type a-law
playout-delay nominal 160
playout-delay mode fixed
cptone IT
timeouts interdigit 4
bearer-cap Speech
In Point-To-Multipoint setup I remove "isdn protocol-emulate network" and "isdn static-tei 0" commands.
Can you add a debug isdn q921?
Is there no response to incoming ISDN SETUP?
Regards.

I got this resolved few days ago, this ended up being a cabling issue.

Hi Chris
Was just going to reply to say it looked like they had cabled two BRI ports to one NTE. Not sure about elsewhere in Eurpoe but here in the UK NTEs have two BRI ports and folks always connect up both ports...
