SIP for telephony using NBN (WIFI)

[Richar]

Hi 

I use a telephony app for work and cant get it to work using my NBN wifi connection at home 

I cant make or receive calls using the app while connected to the modem / NBN optus wifi 

However when i switch to my 4G mobile broadband it works fine 

Can you tell me how to enable SIP through my optus home broadband service please 

thanks in advance

The Optus supplied NBN routers intercept and uses the standard 5060-5061 SIP ports for the Optus VoIP service.

If you are using Optus NBN VoiP service then your VoIP app device will need to be given a static IP address and have ports forwarded to it.

If you are not using Optus NBN VoIP your might be able to do above for the standard 5060-5061 ports, although I don't know it that's enough for the Optus router to relinquish VoIP control on standard ports.

thank you for your response! - although sadly i have the technical aptitude of a minor so i would need that in simple language ... maybe who should i call to sort it out?

Ask your IT people at work, after all, you are using the VoIP app for work.
