Author Topic: How to setup for VoIP -> PSTN calls?  (Read 63 times)

Hi all, I want to connect to my OBI202 using some VoIP method and make PSTN calls from it.

I have:

- OBi202
- Static IP on the Internet and ability to open incoming ports
- OBiLINE and PSTN connection
- OBiBT and Bluetooth-enabled cellphone
- Raspberry Pi that I can load with RasPBX or whatever it required

My OBi202 setup and myself are in different countries.

Example method: I was able to make a call using the green "Call OBi" button in OBITALK to make an outgoing call from OBiBT.

Challenge: This call though went from my browser to OBiHai's server on the Internet and then to my OBi202. This could introduce latency. How do I make this work by making a VoIP call from my location directly to the OBi202 location? Do I need to setup something like this:

SIP phone at my location -> RasPBX on the RPi -> OBi202?

Or does the OBi202 has other methods I can "speak" to it directly?

You can make a SIP call directly from the softphone or through Raspbx into the IP address of the Obi202. If the 202 is behind a NAT router you need to forward the SIP signalling port, usually 5060.

After you get it working you probably want to add some security restriction to the OBi to prevent anyone else anywhere in the world from doing the same.  Smiley
