    hello, i was wondering what your views are on hosted voip versus GSM. I know we are talking about 2 different technologies. However, with a hosted VoIP intercom you can pretty much achieve what you can from GSM. I guess the main difference is cost ? For example with a SIP enabled Intercom you could integrate it to a hosted vop account. You can pick up a single line package for around £5 a month. The intercoms call can route to mobiles ( like GSM). You can also control the hunt groups etc from the internet. For example, just log into your Cloud IP telephone portal and change phones numbers. Do you guys encounter SIP intercoms and hosted voip much ?
