Inbound Calls from PSTN (E1 PRI) to CUCM with MGCP Gateway with VWIC3 Card not working

HemanthKannan

Level 1

Am able to make outgoing calls to the PSTN but am unable to receive the calls from the PSTN.

Out bound Call Flow:

CUCM----->MGCP Gateway------->PSTN      = Outbound calls are fine

 

Inbound Call Flow :

PSTN------->MGCP Gateway-------->CUCM     = Inbound Calls are not working

 

Am not sure what has to configured for the inbound calls for the CUCM.

Can somebody please help out..

Hi.

You need to check Inbound calling search space on Port configuration on MGCP gateway configuration page.

Also I guess you need to configure translation pattern on CUCM to let DDI to be adapted to internal extensions numbering plan.

 

Let me know if you need further info.

Solution :

I have debugged using "debug isdn q931" and found

Calling Party Number i = 0x2183, '9999233888'
                Plan:ISDN, Type:National
        Called Party Number i = 0xC1, '49888803'

In My Translation Pattern i gave it as wrongly as 020498888XX
I changed to "498888XX" and now it is working

Thank you carlo
