HELP ON DIAL PEER DID - GET BUSY ON INCOMING CALLS

[gene.alday]

I've put out a message before, but no responses. I'm trying again.

All I want to do is enable DID on the 3640 router, but when I insert the command 'direct-inward-dial' all incoming calls get a busy tone.

dial-peer voice 1 pots

destination-pattern T

direct-inward-dial

port 1/0:0

The calls are coming in on T1 (MFT-T1).

If someone can help me I can go into further detail. I also have this same message with more detail posted (Aug 28 - DID not working on 3640). Any help would be appreciated, perhaps I am misunderstanding the way dial-peers work.

try putting the FORWARD-DIGITS ALL command as dial peers remove the first digit by default

if this does not work also specify the destination pattern ie 4... instead of T

hope this helps

[gene.alday]

I've tried Forward-digits all and have also tried a defined number like 5551234, however that doesn't seem to work either. Thanks for the response, if you think of anything else please let me know the problem still exist.

Hi,

Can you try the following 3 configurations:

1. On the PRI/BRI interface configuration put:

isdn overlap-receiving

This will enable overlap receiving on the interface in case your Telecom sends you overlap digits. By default the cisco interface receive En block signaling only.

2. See if your 'compand-type' matches on voice-port configuration.

3. Change the 'default route' to:

destination-pattern .T

If this didn't help, try to debug to see the actual problem:

1. To debug the ISDN part use: debug isdn q931.

2. For the H.323 part use: debug voip ccapi inout.

[gene.alday]

It's T1. I've tried to debug 'debug voice ccapi inout' the only error I receive is that there is 'cause =0x1' which I think means no match pattern. I've tried 'destination-pattern T' 'destination-pattern .' destination-pattern 555....' and a defined number. I had matching dial-peers set up for each I've tried.

Thank you for your response, if you have any other ideas please let me know, I am at a loss.

I see too more things:

1. patterns '.T' and 'T' are not exactly the same when related to DID as I remember. Try '.T' and make sure that at the destination of 'session target' the call is routed corectly with the so mached destination number.

2. As I remember the configuration tips you need to dial-peers as a minimum:

a/ one which maches incoming calls with 'destination-pattern .T' which DOES NOT NEED TO HAVE 'direct-inward-dial' on it!

b/ and one which maches the outgoing calls with some prefix 'destination-pattern 052' in my case which MUST HAVE 'direct-inward-dial'!

Here is a working example from my gateway:

dial-peer voice 100 voip

max-conn 6

destination-pattern .T

voice-class codec 1

session target ipv4:192.168.52.2

no vad

!

dial-peer voice 81 pots

destination-pattern 052

direct-inward-dial

port 0/0/0

!

dial-peer voice 82 pots

destination-pattern 052

direct-inward-dial

port 0/0/1

!

dial-peer voice 83 pots

destination-pattern 052

direct-inward-dial

port 1/1/0

And 192.168.52.2 which is a CIsco CallManager in my case, I have the following translatrion pattern defined: 6818XX to be routed to the huntgroup of the secretaries. In my case the Telecom gives me the full LOCAL number of kind '6818..'. This configuration works perfect to me.

In your case it must be something like that:

dial-peer voice 100 pots

destination-pattern .T

port 1/0:0

!

dial-peer voice 81 pots

destination-pattern 9

direct-inward-dial

port 0/0:0

!

If you will use 9 for an outside line.

Good Luck!

Above all what have been said,

Have you created VoIP dail-peer?

That's the dail-peer which should take care of the outbound call leg.

Can you provide us with the VoIP dail-peer?

[eyabane]

I will agree with YRaps. so far you haven't mentioned a word about the Voip dial peer. without it, the incoming call from the PSTN (T1) will die at the router instead of being carried across the IP network. If that still doesn't work, i will suggest you post you configuration so that we won't have to keep guessing.

I am presently configuring the router for store-and-forward fax. If I use this dial-peer, an incoming caller get the IVR 'press 1 for voice or start on the fax machine. This is ok for a DID in which one number is used for both voice and fax. The numbers are 555500X But, what I would also like to do is include a main office number to the operator (5553000), where the caller is not confronted with the fax ivr. In order to do this, unless I am thinking wrong, is to make one dial-peer with direct-inward-dial-enabled. If a caller,(fax or voice) calls 555500X it would be routed to the dial-peer with the IVR. If a caller calls 5553000 it would be routed to the main office number and the operator.

This is the present configuration of the dial peers I am using that works for DID and fax.

i've been a bit slow here sorry, for ip phones you need voip dial peers here is a copy of what we use and it works fine

dial-peer voice 201 voip

From the few line of config that you have posted it appears that you are using cas not pri. meaning that the digits sent one way or the other are sent inband. when you use cas signaling direct inward dial is on for default so there is no need to add it to your config. The dial peer that you have here is for calls orginating of a voip leg and terminating or a TDM leg. If you are trying to get call to come from pbx to a voip end point you need some thing like the following.

dial-peer voice 1000 voip

destination-pattern 1...

session-target ipv4:xxx.xxx.xxx.xxx ( where x is the other end of the voip leg)

on the remote end you would need a dial peer simlar to you orginal one to get the call to terminate on the tdm side of things.

Dial peer need to be in pairs: voip dial peer when it leaves and a pots dial peer when it arrives.
