It would be more proper to compare baresip to PJSIP/pjsua. I'm using both and both are great, with multiple unique features. The strong point for pjsip would be in my opinion pjmedia conference bridge (easy to use and powerful mix

Well, consumer SIP is mostly dead. 20 years ago mobile calls were quite expensive, now they are basically free. Also the marked matured, people are more educated in general and using default port was never a good idea.

V.23 FSK is just the name of modulation. You can have CLIP receiver as separate IC ( https://www.microsemi.com/product-directory/caller-id/4305-m... ) or as some DFT code with Goertzel algorithm with maybe 0.1 MIPS

The other caveat is that time spent configuring, troubleshooting and later maintaining them would be worth much more than 10 dollars. Their use is discouraged by many SIP providers ( https://teamhelp.sipgate.co.uk/hc/en-

I remember these phones had some interoperability issue: https://answers.microsoft.com/en-us/mobiledevices/forum/all/... (technically all according to specification, but often not working for incoming ca

I do believe that Cisco SIP implementation in 7000 series phones is non-interoperable by design. One major issue is that they are sending SIP messages from different port than the port they are receiving on. Because of this they practically

There are some USB "phones" - basically composite USB devices with audio and HID, where HID is used to handle keypad and display (if present). I'm using very cheap EX-03 "Skype" phone: https://tomeko.net&

I think Delphi Started has same limitation as C++ Builder Starter - removed most of debugging functionality (e.g. local variables window). It may be not critical with small applications, but I would rather have "no commercial", no

Not necessary much higher. I've measured screen flickering in Lenovo T500 (probably one of the oldest laptops with LED backlight) with small solar cell and oscilloscope and it's 220Hz, with lowest brightness setting only 100Hz (al

Nope. There is chip looking like PMU on board with at least two output power rails. For VoCore 1 there were two MT3410L converters, one for 3.3V and one for 1.8V. With switching converter total power consumption should be close to SoC power

Code::Blocks was fine for me, simple and lightweight, included in many distros and suitable for cross-platform Windows/Linux work. Also: KDevelop, Eclipse, Netbeans.

With a piece of kynar wire same pin can be connected on "old" ESP-01. Little hard to solder though.

ESP8266 has ADC. It does not have DAC, however for some purposes (e.g. low quality audio over WiFi) I2S output can be used with DMA as PWM output. Isn't IPv6 supported for ESP8266 with lwip?

There are few viewers/editors listed at http://softwarerecs.stackexchange.com/questions/18839/json-v... JSONedit should work well with files up to few MBs, with larger files loading time may be not acceptable

I hope this would be JSONedit as it is mine ;) - http://tomeko.net/software/JSONedit/ There are also - I think two different - plugins for Notepad++, JsonViewer: https://jsonviewer.codeplex.com/ ,

Different uses I guess. I'm using JSON for configuration purposes (~100kB...4MB PABX config, but Azure seems to be more popular example) and it's read-modify-update cycle > 95% of the time.

(Emacs) That's weird. Smart editor should render only portion visible to user and number of lines should not make any difference for highlighter. I've checked Scintilla with 3MB single-line JSON and using C++ lexer (actually: &quo

JSONedit has (experimental) C++ code generator that serializes and deserializes JSON to/from object (default name for class is "Settings" and it uses json-cpp 0.5 as parser and generator): http://tomeko.net/so
