CCVP LAB Question????

Hello All,

I am new to setting up a VOIP network. I purchased a 2621XM router and have the telephony-service configured and have setup my ip phones on my internal network. Everything works but, I want to make a call over the PSTN to my wife's cell phone or any other person from my ip phone and I also want them to be able to call me. If I buy a FXO card and install it in my router will I be able to plug in my home phoneline and make a call out through my router and receive incoming calls to my ip phones as well? Or is this thing going to be much more involved than that?

Hi Charlie,

No problem. Getting into voice can be a fairly daunting task sometimes.

Glad I could help - please remember to rate helpful posts so that others that use this thread as a reference will be able to navigate it easier.

Re: CCVP LAB Question????

Yes, you can get a VIC-2FXO or something of the sort and that will work. Keep in mind that you need DSPs for this to work as well. You could get something like a NM-HDV, NM-2V, or NM-HDV2 and that would have onboard DSPs.

Hey Nic,

What is are DSP, NM-HDV,NM-HDV2 and what does it do?

Re: CCVP LAB Question????

DSPs turn analog traffic into RTP.

They are required for conferencing, transcoding, MTPs, and any analog voice pots connections.

Here is a calculator:

They do the Digital Signaling Processing:

Re: CCVP LAB Question????

Hey Nick,

I went to see what you were talking about. On Ebay the DSPs are still expensive. If I don't have that module the digital to voice conversion will not happen right. This will make what I am trying to do not work at all whenI am calling from a IP Phone to a PSTN phone. Am I understaning everything you have told me?

Re: CCVP LAB Question????

Hi Charlie,

Unfortunately DSPs are quite expensive. It surprises a lot of people, and we see a lot of people who think they're ready to do voice but then wonder why their analog ports don't show up in the configuration.

The NM-2V is probably the cheapest because it has non-replaceable DSPs on port.

There is also the NM-HDA which has DSPs.

At least you prevented yourself from buying a card without knowing the consequences :)

Re: CCVP LAB Question????

Hello Nick,

Which one would you reccommend I purchase for my 2621XM router?

Re: CCVP LAB Question????

From a quick search, it looks like a NM-1V is going to be the cheapest option. NM-1V + VIC-2FXO.

Glad I could help out :)

Hello Nick,

I just bought both of those cards like you told me to do. Hopefully they will be here by Monday or sooner. Is is ok if I contact you directly when I get this stuff if I find I need your help? Also know that I have purchased everything you told me to, do I have everything I need to make calls over the PSTN using my phone line from home?

Re: CCVP LAB Question????

Hi Charlie,

You should be able to post a new topic here if you run into problems. Once you put the VIC-2FXO into the NM-2V and put it in your 2600 with an ipvoice or better image, you should be ready to configure voice.

Good luck!

Re: CCVP LAB Question????

Hello Nick,

Are you a Cisco Voice Expert and it so can I get my CCVP with everything I currently have?

Re: CCVP LAB Question????

I'm not a CCIE..yet.

It's hard to say. I've worked on all this equipment via being on calls with customers, so I'm not sure what type of lab equipment is required.

I would suggest getting a VMware server configured so that you can set up a Callmanager. You could then download multiple IP Communicator clients and do all types of stuff with that.

You could use your 2600 as a SIP/MGCP/H323 gateway as well as a CME. I think with VMware plus the gear that you've ordered you'll be able to look at quite a bit of voice.

Nick,

I am so glad to hear that. I had no idea if I was going in the wrong direction or what. Now after speaking with you I have been reassured I have not been wasting my money and time. Thanks Again for everything you have done because without it I had no idea how I would have gotten this far with my Voice Lab setup. Thanks sooooo Much Nick. :) :)
