Voice over IP services are getting to be increasingly popular, as people realize the advantages that internet-based telephony may offer them. Small businesses are specially good candidates for VoIP services, for two reasons. Aside from the usual suspects, like lower overhead, VoIP has some unique features that produce is very attracting business owners.
Phone System - If you curently have an IP based PBX then healthy for you when you won't invest for this aspect, however are a starting business or someone who just ditch a regular telephone then it is better that you simply couple a SIP trunking platform with a hosted PBX as it involves less investments, basically all you have to are a handful of IP phone handsets or soft phones, programming hours from the service provider, the best connection to the internet and you're simply good to go.
But this is where the real difference comes about, since the softswitch sip.us won't pass your phone call to only travel by using normal telephone lines. It will have the internet. This is how the SIP trunk service basically works. So, the question for you now, why bother getting this service if it does the same function as normal telephone system?
As for routers, I like the Cisco WRVS4400N gigabit router. Trust me, the wireless router provided by your web provider may work, but it's not high enough quality for business needs. Good cabling is going to be needed to enable you to get the top transmission over your network. Category 6 is the thing that I recommend. I am always amazed when business owner/IT manager can't answer questions about the type of cabling he/she is utilizing or who installed it. You can have the very best IT equipment, in case your cabling is poor, it will be all for not.
The agency you're going through acts because middle man, between you and the companies who's services you would be using. You tell them what exactly you need, and they'll sort everything out relating to the agencies. Everything will likely be put under one particular contract, giving you additional time to focus on running your company. It also gives an ease of mind, if you know for most issues, there is certainly merely one place you must require help.
