[SIPForum-discussion] HOW TO IMPLEMENT SIP ON OUR IP TELEPHONYTELEPHONE SYSTEM

[Pinakeeb]

Reggie,

 

Choose a PBX that supports SIP. Asterisk is one of them and is an open
source freeware. You can install the same in your company if you want
something free and minimum cost. 

 

Avaya, Cisco etc. are some companies who are leading vendors in IP PBX. You
can get the quote from them. 

 

 

Remote users can download free softphones on their PCs (if they have one)
and that will free of cost. Softphones can be used to make calls via your IP
PBX. There are hard IP phones but they come with a price tag. 

 

Cheers,

Pinakee

Hi All: 

The company that I work for will be moving next month to another building as
a result we have decided to go with another telephone company. Our new
telephony system will be  an IP Telephony IPBX system. Initially we were
told by them that with an IPBX IP telephony base system our remote users
that work from their homes will be able to make calls over the public
internet through our IPBX box with an IP Telephone that will be provided by
them, just like Vonage. 

Now they are telling us it won't be so simple as additional hardware will
have to be purchase that will cost us over $10,000. I'm not convince that
this is the case. So my question does anyone have an idea how we can get
this to work using the SIP protocol that I have been reading about with IP
Telephony IPBX telephone system, thank you?
 
Kind Regards
