Help Select Cisco Voice Gateway for Switchvox IP PBX
I need to purchase a Voice Gateway for a new Switchvox IP PBX system that will be connected to PSTN and a SIP trunk. Our network is primarly administered by an outside vendor that is a Cisco dealer so I would want the unit to be Cisco. This will be replacing a PIX 515 and also needs to handle Firewall and VPN needs for our network. I will be getting the vendors recomendation but I would like to do enough research to understand that what they propose is right for us and be able to ask questions. So I am interested in getting suggestions on what you would suggest is the best Cisco Voice Gateway model for my needs and why.
It depends a lot on what kind of connections you have to the PSTN and the amount of volume needed. Normally, I use a 2800 router for voice. Make sure you have enough DSPs for each channel and any encoding you may be doing. I don't recommend using the same router as a firewall though. You might be better off keeping the PIX in place to protect the network.
based on how many PSTN line do you have and the type of them also, then you can select one Cisco integrated service router with voice/security bundle. starting from 2801 up to 3845

The proposal I have from our Cisco vendor includes the following equipment:
Cisco 2811 Voice Security Bundle - Router - voice / fax module - EN, Fast EN - Cisco IOS - 1U
Cisco Multiflex Trunk Voice/WAN Interface Card - Expansion module - 2 ports - T-1/E-1
Cisco Voice Interface Card - 4 Analog Ports
Cisco Catalyst 2975 LAN Base Switch - 48 ports - 10Base-T, 100Base-TX, 1000Base-T + 4 x SFP (empty) - 1U - PoE - stackable (pack of 2 )
Cisco Wireless LAN Controller 2112 - Network management device - 8 ports - EN, Fast EN - 1U - 12 Access Points
Cisco Aironet 1131AG - Wireless access point - 802.11b, 802.11a, 802.11g
Cisco Aironet 1242AG Lightweight Wireless Access Point - 802.11b, 802.11a, 802.11g
Cisco Aironet Antenna - 2 dBi - omni-directional
I have been looking into adding a Cisco ASA 5510 IPS Edition to this list as a replacement for the PIX. Is that a good idea? I am a little worried about the ease of management of this devise? Our vendor tells us that it continually updates security signatures and requires constant monitoring. They want to sell us a managed security contract for the ASA that I would pay out the nose for. Do you think that is necessary?
