Grasshopper vs. Kamailio SIP Server

Grasshopper is well suited for basic needs of texting in and out as well as calling out if you would like to avoid using your personal line. It also eliminates the need to have a dedicated land land in your office or business. You can obtain a vanity number and forward calls through grasshopper.

Kamailio SIP Server is very well suited if you want to secure your main servers; it can perfectly act as a proxy server and a gateway to your main server. It also does load balancing and call transfers easily based on the configurations done.

• I like that there are differing voicemails for each extension, to keep up with the image of calling a separate line.
• I love the voicemail text emails. I believe we pay a little extra, but worth every penny for those urgent calls while I am in a meeting.
• The cost is very reasonable for the value added to our company.

• It would be nice to have the ability to transfer some calls to another Grasshopper IVR, for those customers who mistakenly dial the wrong number (we have two incoming numbers, one for corporate and one for sales).
• Likewise, it would be nice to have the ability to forward to a toll-free number, which would have allowed us to work around the inability to transfer between IVRs (see above).
• Lastly, it would be great to have an 'emergency' switch setting (default off but could be toggled on) that would let us override all IVR settings and transfer all incoming calls elsewhere (either to a direct dial or toll free number) for those rare times when we cannot take any calls (such as a weather emergency OR the one time each year we take all of our staff on a retreat) - that would allow us to send all calls to a backup answering service rather than just voicemail.

• Interportability
• SIP conversions.

The admin functions are kind of confusing in the old interface which was my most recent experience on the admin side.

When I was setting up my account I contacted support a couple of times. They were also very professional, personable, and helpful. Their response is prompt and thorough. I'm confident I can get any question answered as well as help with any issue I might have. That's pretty important to me.

I have not used any other phone services like Grasshopper. I know that there is another option out there called Ruby, which is more like a virtual receptionist but since I did not try it out I cannot compare the two. When I started my company I found the services that Grasshopper offers to be perfect. It still works for us and we have no need to change to anything else right now.

As Kamailio SIP Server is an open source, the major impact is on cost; it's free to use compared to any other Softswitch or server in the market. You can also customize it to your need and use the features that you need, which is one of the major plus points for the Kamailio SIP Server. And one server is enough to handle thousands of calls simultaneously.

• It's allowed us to keep cost down. Other phone systems can seriously get outrageous in implementation and monthly fees!
• It's allowed our team the confidence to work in locations outside of the office and still be seen as professionals.
• It's decreased the amount of time spent on unwanted sales calls via the call screening application.

Incentivized

• As its open source ROI is excellent.
