Tips about SIP Softphone on Smart Phone:

Low bandwidth codec:

As Smart phone use Wireless network connection either WiFi or 4G/5G, but might not be stable enough in places with poor sighnal. G729, G722 or Opus codec is recommended! 

However, G729 is old technology, which may increase CPU’s payload. The voice is actually lossy due to compressed too much. Opus becomes popluar recently years because it’s with ultra-low bandwidth, low CPU payload and high-quality voice, so set Opus as the 1st priority if possible.

Text message

Many softphones support SIP message, which could be as alternative of  cellphone’s text messge, but some institutions like banks don’t send a vertification text message to a VoIP phone number.

Push Notification

Either iPhone or Android will kill the app in the background  to reduce energy consumption.  If the softphone was killed after display turned off some time, you could’t receive an incoming call. Fortunately, software could be woken up via push notification, which replays on Apple or Google notification server and will increase developper’s costs. This is why free softphone usually doesn’t come with push notification. 

Moreover,  phone consumes less power if using push notification.

Energy Consumption

UDP or TCP

SIP softphone usually uses either UDP or TCP protocol to connect PBX server. TCP consumes less energy. UDP is default in most softphones, so you need to change UDP to TCP in settting if your PBX server supports TCP protocol.

Keep softphone runing in backgound?

At present, only Android phone allows software or other apps working in backgound. iPhone seems to allow it in a little more time, but still kill softphone in background after display is turn off  long time

Conclusion on SIP Softphone on Smart Phone

You can use free SIP softphone for personal or hobby use.

However you should buy a paid softphone with G729 and Push Nortification for business use.

PBX on Chromebook

PBX on Chromebook PBX on chromebook works great! Especiall for the chromebook with x86 CPU.  Most IP-PBX are developed on x86 PC first. Linux distro also developed on  instruction sets of x86 CPU. Therefore, you’d better to choose an x86 PC or chromebooks for your first PBX server.   Google usually supports chromebooks about 5 years. Afterwards these chromebooks wouldn’t get the update on system, chrome browser and security. Lots of old chromebooks were dumped into 2nd-hand market every year. You could spend less than 50 dollar to get an used or refurbished chromebook from ebay, Amazon or bestbuy. However it will bring security issue if these old chromebooks wouldn’t get securty update from Google. Can we swipe off Chrome OS and install Linux, then modify it to a PBX server?
