The CUCM my company is interconnected to the network of a telecom operator with a link QSIG E1.

Our internal network we can call external numbers via the QSIG link. But we can not receive the calls from operator through this link.

debug q931 give me:

Jul 16 14:05:24.939: ISDN Se3/1:15 Q931: RX <- SETUP pd = 8 callref = 0x008E

Sending Complete

Bearer Capability i = 0x8090A3

Standard = CCITT

Transfer Capability = Speech

Transfer Mode = Circuit

Transfer Rate = 64 kbit/s

Channel ID i = 0xA18389

Preferred, Channel 9

Calling Party Number i = 0x2183, '7723693'

Plan:ISDN, Type:National

Called Party Number i = 0xA1, '2607'

Plan:ISDN, Type:National

Jul 16 14:05:24.943: ISDN Se3/1:15 Q931: TX -> RELEASE_COMP pd = 8 callref = 0x808E

Cause i = 0x8081 - Unallocated/unassigned number

Jul 16 14:05:25.935: ISDN Se3/1:15 Q931: RX <- ALERTING pd = 8 callref = 0x8146

Progress Ind i = 0x8488 - In-band info or appropriate now available

The operator can send me that 4 digit which is normal. The number called, 2607, are on my call manager

my gateway:

!

controller E1 3/1

pri-group timeslots 1-31 service mgcp

description ZAIN

!

interface Serial3/1:15

no ip address

encapsulation hdlc

isdn switch-type primary-qsig

isdn incoming-voice voice

It looks like there is no Incoming CSS on the MGCP-GW selected, or the selected CSS has no access to your phones partition.

Check in CCMAdmin under Device/Gateway/"Your MGCP-GW"/"Your Endpoint" if there is under Call Routing Information - Inbound Calls/Calling Search Space the right CSS selected.

Hello philippgrafl

Thank you for your reply.

I check the CSS of the gateway as you suger. I used the CSS LO.

All my phones are in the internal partition and CSS LO contains this partition.

Clearly the problem is not there.

How can I do to see the logs of CUCM to find out what is blocked. With the tools RMTT I will what tab?

The best way is to use the DNA for Gateways. Set up the DNA to simualate an incoming call to the GW from outside- the caling party can be anything- the dialled digits are the numebr you wish to test for. The CSS is the CSS of the GW. Check the results also do a route plan report or a directory depending on the CUCM SW level-
