Direct Inward Dialing problem!

[etayeb_dd]

Hello,

I'm trying to get Direct Inward Dialing to work on my Cisco 2650 with a NM-HDV-2E1-60. Outgoing calls work just fine, but incoming calls are not routed.

I read http://www.cisco.com/warp/public/788/AVVID/did-and-callmanager.pdf but it did not work.

Here are my dialer peers so far. The telcoswitch delivers 4769[3-digit-Extension] to the router as called number.

dial-peer voice 1 pots

application mgcpapp

port 1/0:15

!

dial-peer voice 2 pots

application mgcpapp

incoming called-number 4769...

direct-inward-dial

!

dial-peer voice 3 voip

application mgcpapp

destination-pattern 4769...

session target ipv4:[IP-of-CCM]

codec g711alaw

[prasannac]

Add the port no in dial-peer voice 2 pots

Unfortunately that did not work. Here is a q931 debug output:

Add 'incoming called-number 4769...' to your voip dial-peer instead of pots

[tarun.pahuja]

Dial-peer 2 is missing the Voice Port.

If i were you, i would make it simpler.

Dial-peer voice 1 pots

aplication mgcpapp

incoming-called-number .

port x/x:y

No need for dial-peer voice 2 pots

Then control the digits to be accepted at the gateway level.

[tarun.pahuja]

Forgot to mention that you can include "direct-inward-dialing" statement in dial-peer 1 itself.

Thanks

Hello ,

Make sure in the call manager gateway page for inbound calls correct calling search space is choosen.

Thanks,

OK, I changed some things:

The gateway now receives all digits of the called number, but only reads the last three, the extension. It is in the same CSS as my phones (PhoneCSS), but still no luck!

And why keep I getting this q931 error when I receive calls?

Hello,

Do you have "isdn overreciving" command on the int serial1/0:15 of the ISdn ?

Take a look at the following link

What did I do wrong? Outgoing calls work just fine!

[tarun.pahuja]

Please modify your VOIP dialpeer. Destination pattern is not correct. It should be more than a ".".

if your internal numbering sceme is 3xx or 4xx,etc make sure your destination pattern under VOIP dialpeer says 3.. or 4..

Also, your debugs show that the telco is sending you 7 digits, your POTS dialpeer is accepting all digits, make sure that you accept only the last 3 digits at the gateway level or modify the POTS dialpeer.

Also, you might want to consider Radhika's advice regarding ISDN-Overlap.

Here is the Doc.

http://www.cisco.com/warp/public/788/signalling/isdn_overlap_prob.html

after you make the changes, try calling from the router using csim start xxxx command to check if it is a gateway/CCS issue or PSTN signalling issue.

Thanks

Thanks,

[rnarayana]

Hello ,

One more thing.On the callmanager gateway configuration page for inbound calls verify the number of significant digits are correctly set.

Thanks,

Radhika.
