SIP protocol and state expert

Job Description:

we are looking for a exceptional good expert about SIP protocol and SIP states.

Your task will be to help us to identify things on SIP to be able to discuss with our developers (with low expertise on SIP). The developers have to implement some features, but do not understand the SIP protocoll well to find the correct paths.

Your task will be to help in the discussions about low level SIP featuers like:

- how to list all registered SIP devices (softphones, smartphones-apps, desktop-apps, physical phones, ...)

- how to identify how many onging calls are running in parallel?

- how long is each call onging?

- who (device) has taken the call, what time ended the call, ...

- and many more

Your task will be to consult only, except you are a developer too. If this is the case, you are welcome to join too after going through a interview call+test task on development.


we do not disclose our budget, place your best bid to get considered
