  • 2811 Brand new router, what modules to buy?

    Hi, guys, new in Cisco world and in your forums!

    I am willing to buy a 2811 Router, brand new in the box.

    In order to study VoIP, what other modules do i have to buy?

    1x VIC2-2FXO 2-Port FXO
    1x PVDM2-16
    1x Cisco NM-HD-2VE Voice Fax

    Are the above correct?

    Do i need all these to start studying?

    If yes, what firmware i must run on 2811? How i can implement CallManager 4 into the router?

    I already own a 3750 PoE Switch.

    Sorry for all the n00b questions...

    Thanks

    You are on the right track, but there are many flavors of VoIP implementtions. Based on the scope of your post, I would purchase the 2811 voice bundle. This would include the proper IOS (with CME licensing), and DSP's.

    Checkout cisco part number:
    PN=CISCO2811-CCME/K9
    DESC=2811 Voice Bundle w/ PVDM2-16,FL-CCME-35,SP Serv,128F/256D

    The FXO card will allow you to coonect to LEC via a POTS line
    The FXS card will allow you to connect an analog phone or fax
    The 1MFT card will allow you to connect to LEC via 24 channel PRI

    Since you already have a 3750 PoE and your scope is to start studying VoIP, I would look at just purchasing a simple 2801 Voice bundle along with a couple of IP phones (like 7941's). This will give you a good start at configuring Call Manager Express, Dial-Peers, Voice/Data vlan's, dot1q trunking, QoS and so on. When your studies grow to integrating your VoIP infrastructure into a LEC PSTN, then look at purchasing the FXO or 1MFT module.

      I already have 2 7970G phones, I will buy the bundle and I'll start studying!

      After buying it, can i download firmware and CME updates from cisco.com or i ll have to buy a contract from them?

      "The FXO card will allow you to coonect to LEC via a POTS line"

      What is LEC? By using FXO card, can i connect it to my PSTN line and receive calls from the outside world to my 7970 phone?

      Do i need to buy "
      Cisco NM-HD-2VE Voice Fax" in order to use FXO card, right?

      Thanks for you reply, and sorry for all those n00bish questions...

        Yes, you will be able to use FXO card to connect to PSTN and route calls to IP phones.

        Sorry for confusion on my terminology, LEC=local exchange carrier (like verizon, AT&T, etc..)
