Cisco IP Phones vs. Kamailio SIP Server

We have found so many use cases for Cisco IP Phones and have not come across too many situations where they were not well suited, other than being mobile. We have moved to another Cisco Solution for Mobile communications. We have phones all over the place, in offices, in clinical areas, in lobby or public areas, and even in all of our conferencing and meeting spaces.

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.

• So while the 6800 range may not offer slick features, it still provides all the core functionality that businesses have come to expect from their VoIP handsets.
• Most of the handsets that make up the 6800 series do come with a greyscale display, which may be disappointing if employees are used to working with color VoIP solutions.

• Interportability
• SIP conversions.

i think it's profitable and a good return on investment as a person who make an architecture based on VOIP with IP phones i really enjoyed the process of configuration of the router , the switch and everything and then when i had to test the communication between two phones I've configured it was a joy. Also it's a good phone to receive and give calls to our clients.

Easy to use Functions are self-explanatory Light Efficient I generally have no complaints about them as they get the job done. Just a few employments on maybe graphics or so otherwise they are really great 👍 no complaints... Maybe it is just because is just a user and doesn't implement them or something.

The 8800 series phone is lighter and has a better build quality with all except the flagship phones from Yealink, Mitel, and Avaya. The Yealink S59 and Avaya Vantage have a touch screen interface the make them more akin to the old DX650 which is more high-end than the 8800 currently.

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.

• I set up the desk for new hires in our group - it is super easy to plug in this phone and have them up and running.
• Having the ability to pre-program speed dial numbers ensures that new hires are able to reach help without having to search for a number.
• The ability to program ring tones is great, so if we are in the shared space meeting and we hear a phone ring, we know who's phone is ringing - the meeting can go on without everyone leaving to check.

• As its open source ROI is excellent.
