Need a Messaging application

hi and thank you for the comments,

cdesigner > i've been using openfire/spark for the past few months now, and i do like it but it's missing key features which i'm desperately in need, it could be an available option which i don't know how to enable, maybe if you have some knowledge using openfire/spark, maybe u could help?
the key features it's missing are:  being able to login from multiple devices at the same time to the same user account. seeing the message history on all devices regardless of where you login and when you login. how a sign when other user is typing.

Merete > i thought about the ability to use these systems, and i don't mind using them, but is there a way to disable all options to be able to login to other services like hotmail, yahoo, etc... because i know these services support other messaging systems at the same time; if i use them for business, i will have a problem with users loging into other services and wasting time during work hours. and i can't monitor these users all day long.

thank you guys for your suggestions, both suggestions are nice options, but still hoping to find something, or modify spark to do what i need, which makes it the perfect system for me.

Hotmail is obsolete and replaced with Outlook.com

Messenger has moved to Skype

How is it your clients are still using it?
Trillian im opens to a page/panel there you choose which to log in to.
Like Hotmail you can select who to add as your contacts and who not to have

i didn't say anything about hotmail..!

i don't have clients using anything, this is only for internal use in the company. i want a solution where i can login from my mobile and 2 computers at the same time, and msg some of the other users in the company, when they reply back to me, i want to see the msgs on all my devices. i'm not interested in using skype or any public messenger as that will destroy my company. all my employees would be adding their friends and family on skype, they can chat with them during work; bad idea.

until today i have not been able to find anything with the specs i'm interested in.

Hi Giggz,  internal use in the company.
Like a Lan messenger?
have a look
Office chat

Bitrix24
Instant messages, group chat, file sharing, voice calls, video calls, videoconferencing, telephone calls, mobile messaging for Android and iOS

WinPopUp
send Messages Securely, Strictly Within Your Local Network
No Internet Connection Required

Merete, thank you for suggestions,

winpopup won't work for sure, as it's only for computers, i want to be able to send/receive msgs on mobile devices, as some of us are outside the office.

office chat, seem to have all the features i need, except it's not self-hosted, which means there is a cost to use it for our users, even though they do have a free basic option, i'm unsure of the limitations in it. also because we send sensitive data, i don't want a third-party to host the chat history for me for security reasons. so this option wouldn't be suitable for my situation.

bitrix24 i will have to dig deeper into their settings and test it out for a day or 2, i don't care much for the voice/video stuff, i only need chat and file sharing is a bonus. but it seems to be the closest to what i need so far. i will test it out this week and will reply back with my opinion.

if anyone else has any other close self-hosted solutions, please don't hesitate to let me know.

thank you all

they are both based on xampp, which both don't support multi-user concurrent logins.

i also investigated bitrix24 and it also doesn't have the requirements we need either.

:(

any other suggestions, anyone

Did you see Bopup IM? Probably it answers to all of your requirements.
