InboundCall on E1 port

[moaz_elgammal]

Hi all ,

I have CUCM v9.1 and  Cisco2921 as a MGCP gateway to access PSTN through two E1 ports. I don't have a problem on Outbound call.

For inbound call ,

My number of E1 is 269408XX ,  the extension schema of ip phones is 08XX , but I can't make a call and this error comes out.

debug isdn q931 is              ON.

Hi

Please check the significant digits & the CSS fiedld on the MGCP endpoint configuration

[moaz_elgammal]

The significant digits are 4

[Suresh Subramanian]

ok, that should be fine. you have the right inbound css assigned?

also do you apply any translation pattern for these inbound calls before routing them to the ip phones?

[moaz_elgammal]

No , i don't have any inbound CSS assigned and i didn't apply any translation pattern .

I think I don't need translation pattern becuase i use this schema on ip phones 08XX , 

[Suresh Subramanian · Accepted solution]

You should have Inbound CSS containing the partition of those extensions.

ex: lets say if the extensions are in 'PT_Extn' partition then create a css as 'CSS_Inbound' add the 'PT_Extn' to it. Assign the CSS to GW for 'Call Routing Information - Inbound Calls'

This look like partition/css issue. Check this thread - https://supportforums.cisco.com/thread/2007133.

Thanks
