Cisco VoIP Question 1

[Bubbalouie]

Hi,

I'm running a Cisco 2800 series router running IOS Version 12.4(15)T9, RELEASE SOFTWARE (fc5).

I have been told I need to disable users from calling in to their mailboxes from the outside and starting a new call from their vmail box.

What is this feature called and what do I do to disable it?

Thanks In Advance

What are you using for your VM, CUE?

I actually don't know the answer to that and the guy who installed the unit seems to be unreachable.

The only thing I can tell you right now is that there is a 'voice mail module' built into the router that handles it.

Is there a 'show' command that would tell me that info? A show ver gives me this:

Cisco 2811 (revision 53.51) with 245760K/16384K bytes of memory.
Processor board ID FTX1337AJJ6
11 FastEthernet interfaces
1 terminal line
1 Virtual Private Network (VPN) Module
8 Voice FXO interfaces
1 cisco service engine(s)
DRAM configuration is 64 bits wide with parity enabled.
239K bytes of non-volatile configuration memory.
126000K bytes of ATA CompactFlash (Read/Write)

Ah! I'll bet CUE = Cisco Unity Express.

I'll look and see if there is a show command for that.

Hi,
Maybe this Cisco doc will help - Link

I'd say that's the document based on the title alone!!!

I noticed this part right off the bat:

--------------From Cisco Document--------------
Incorrect Configuration:

If you configure an inbound dial-peer, as in the sample configuration in this section, the possibility for toll fraud still occurs. The problem with this inbound dial-peer is that it only matches inbound calls to 40852512.. and then applies the DID service. If a PSTN call comes into 40852513.., the inbound pots dial-peer does not match and thus the DID service is not applied. If an inbound dial-peer with DID is not matched, then the default dial-peer 0 is used. DID is disabled by default on dial-peer 0.

Sample Configuration

dial-peer voice 1 pots
incoming called-number 40855512..
direct-inward-dial

Correct Configuration

The correct way to configure DID service on an inbound dial-peer is shown in this example:

Sample Configuration

dial-peer voice 1 pots
port 1/0:23
incoming called-number .
direct-inward-dial


-------------My Config------------------

dial-peer voice 1 pots
incoming called-number .
direct-inward-dial

In the sample config they are using a T1 PRI whereas I am using 3 pots lines.

I'm guessing I need to add the port command that my config is lacking. I have the following ports:


voice-port 0/0/0 - 0/0/3

voice-port 0/1/0 - 0/1/3

that's a total of 8 ports though only three are actually in use. I of course won't know which 3 unless I jump in my car and make about a 4 hour round trip!

Can I just add the ports like this:

port 0/0/0:3
port 0/1/0:3

If I do add those ports like that, will that take care of my Direct Inward Dial problem which I suspect we have?

 

[Bubbalouie]

Well, it appears I can't add them in that format. I also tried 0/0/0-3.

The only way I could get them to add was to use this format, 0/0/0 or 0/1/03 which converted to 0/1/3.

Also, also when I added the second port command it overwrote the first so I wound up with only port 0/1/3.

Is there a way for me to add a range that would cover all 8 ports?

Hi,
You need to setup a dial peer with a preference for each port.


dial-peer voice 1 pots *** No preference defined = 0 which means highest priority
incoming called-number .
port 0/0/0
direct-inward-dial

dial-peer voice 2 pots
preference 1 *** Second priority
incoming called-number .
port 0/0/1
direct-inward-dial

dial-peer voice 3 pots
preference 2 *** Third priority
incoming called-number .
port 0/0/2
direct-inward-dial


Hope this helps
