Hello:
I am trying to connect a ISDN Phone to a bri port in a VIC2-2BRI-NT/TE, but the calls doesn´t work in both direcctions. The VIC is installed in a MGCP GW.
Here is the configuration that I am using:
interface BRI0/2/0
no ip address
isdn switch-type basic-net3
isdn overlap-receiving
isdn protocol-emulate network
isdn layer1-emulate network
isdn incoming-voice voice
isdn skipsend-idverify
line-power
end
voice-port 0/2/0
cptone ES
bearer-cap Speech
show isdn status bri 0/2/0
Global ISDN Switchtype = primary-net5
ISDN BRI0/2/0 interface
******* Network side configuration *******
dsl 8, interface ISDN Switchtype = basic-net3
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 64, Ces = 1, SAPI = 0, State = TEI_ASSIGNED
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 8 CCBs = 0
The Free Channel Mask: 0x80000003
Total Allocated ISDN CCBs = 0
When I call the number of the phone from a DN of the call manager I have the following output from the debug isdn q921 and q931:
Sep 7 10:55:39.455: ISDN BR0/2/0 Q931: Applying typeplan for sw-type 0x1 is 0x0 0x0, Calling num +XXXXXXXXX

Sep 7 10:55:59.575: ISDN BR0/2/0 Q921: Net RX <- RRf sapi=0 tei=64 nr=0undeg
I don´t know why is not working since I am using a typical configuration for this.
What I am doing wrong?
Best Regards.

The Layer 2 shows TEI_ASSIGNED status , that's the reason calls are not working. The Layer 2 status of PRI/BRI should be MULTIPLE_FRAMES_ESTABLISHED. You need to share the running config to check for any issues with that.
