I am configuring in Cisco Router 3945 with E1 Qsig to contact a MITEL 3300
This is the configuration:
isdn switch-type primary-qsig
controller E1 0/1/1
framing NO-CRC4
clock source internal
line-termination 75-ohm
pri-group timeslots 1-31 service mgcp
description Mitel
interface Serial0/1/1:15
no ip address
encapsulation hdlc
isdn switch-type primary-qsig
isdn overlap-receiving
isdn incoming-voice voice
isdn bind-l3 ccm-manager
no cdp enable
voice-port 0/1/1:15
echo-cancel coverage 64
cptone MX
timeouts call-disconnect 0
timeouts wait-release 1
description QSIG - Mitel
dial-peer voice 503 pots
incoming called-number .
direct-inward-dial
port 0/1/1:15
when i connect the E1, the E1 up but i can not receive calls and make calls.
This configutation is correct for connect to E1?

Hi Julio,
Can you try making the Cisco end of the link network mode.
One end should be user and the other network
Usually PBXs will default as "user" as the PSTN/SP-Nets are
always "Network". So one end needs to act as the NETWORK side
in order to allow the operate.
MITEL (USER) ------------------(NETWORK) Cisco
On your CUCM admin pages set the mgcp end point
"Protocol Side " field to Network
Update and reset
On the router config
!
interface Serial0/1/1:15
shut
isdn protocol-emulate network
no shut
!
no mgcp
mgcp
!
Retest calls
Hope this helps
Regards
Alex

Hi
Can you share " show isdn status" & "debug isdn q931"?. We need to make sure that layer 1 and layer 2 are up. Other question can you share your design ?. We need to know after the call come it will transfer to IP phone using MGCP & H323 or you solution CME based.
Thanks
