HCL Sametime vs. Kamailio SIP Server

Sametime is well suited for very quick conversations, where you know the person is an active Sametime user. It also serves as an easy way to reach out to someone you may not know when looking for an answer to a quick question, as they are likely to be a Sametime user. Do not, under any circumstances, attempt to use Sametime for Audio or Video chat. The quality and reliability are horrendous.

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.

• Sametime's web-based interfaces are "zero load", requiring no plug-ins to be installed to join a meeting, launch a meeting, or use chat in a browser. A plugin is required only if you want to share your screen.
• Integration with IBM Notes is very tight. Sametime's chat status can change according to your Notes calendar. You can easily see if someone who just emailed you is available to chat. Your chat History is right inside Notes as well.
• IBM's mobile apps are top notch. We automated the apps for our users thanks to IBM's work with third party MDMs. This made it very simple for us to deploy the Sametime mobile apps -- Chat and Meetings -- and get new capabilities such as Audio & Video mobilized quickly.
• No down time, ever. The rock solid WebSphere back-end of Sametime means the environment is always up. Period.

• Proxy server.
• Security Firewall.
• SIP to PSTN gateway.

• High speed connection is needed to connect to Sametime

• Interportability
• SIP conversions.

Sametime is now an embedded experience for our users. They know it, they like it, they use it, and they expect it to be wherever they are. Because it is pretty easy to use and NEVER goes down, users know they can rely on it and won't be frustrated by it. Sametime is right up with there with Microsoft Office in terms of user adoption and appreciation.

Just about everything works the way you expect it would and it's relatively easy for users to figure out. Sametime was one of those things that we started with only a few people as a "test" and before the test period was done we discovered a few hundred people had figured out how to log in and most got it working all on their own. Many of our users want to use Sametime and do so regularly; we do not have to create policies enforcing its usage. Users find it practical to use Sametime to do things like chat, transfer files, share their screen, and so forth.

Typically if Sametime is not available, it's because Windows Updates were done on the servers and they were not rebooted. However, that's not a problem with Sametime -- in fact, if you have Linux you could probably run Sametime for years without any hiccups whatsoever. We have no internal Linux expertise.

Generally very good. Occasionally AV or screen-sharing will stutter and every now and then I hear of it dropping out altogether, but in all cases it was easy to re-establish

I have not needed to use the Sametime support team. Our local support team was able to configure it for me.

We use Jabber globally in our company and Symphony (no relevant app in able list) in some of the teams as well. All these are instant messenger tools, but Sametime is the easiest one to be used and its chat history is easy to be searched. Sametime can be used to contact almost all internal staff as it’s included in default computer package. Symphony is used to chat with front end business while Jabber is used for call.

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.

Sametime is rock solid. It runs on WebSphere, DB2 and other related IBM technologies. This does mean the back-end is highly complex and very difficult to learn and get comfortable with, however.

• Sametime keeps many of our team members in contact throughout the day which leads to increased productivity which makes everyone happy.
• We use the team chat room feature every day. This allows a team to stay focused on the task without any extra messages that are not on topic.
• The split between IBM Sametime, Slack and Google Hangouts has caused some issues when team members are not checking for messages on a certain app.

Incentivized

• As its open source ROI is excellent.
