Hello,
I purchased the router as above to test functionality (we will need more devices if it works). I was hoping that I will receive incoming SMS over SMPP but that’s not the case. I am reading some posts like this or that suggesting that receiving SMS is possible.
I have bound my SMPP client as the transceiver but I could.
Is it possible to receive Inbound SMS over SMPP. which devices support that ?
thanks in advance
Hello @csiwekk
look at this.
In short: SMPP solution on Teltonika devices not support receiving SMS globally (universal).
the message would have to be in a specific format (this work) - user ID:message - <id>:<message>.
the solution is to use the api for read received SMS - Teltonika Networks Web API
Greetings,
Thank you for the input @netservice
@csiwekk, has your inquiry been resolved, or do you have any additional questions?

Thanks for the answer.
How hard would be to implement the smppd to be passtrhough?
We did openwrt development before and we would like to contribute. This is quite important feature for us.
@Justinas would you be able to provide sources of smppd? I don’t mind signing an NDA if those are not open.
Greetings,
I have forwarded your inquiry to our research and development department. Once I get feedback from them, I will get back to you.

Greetings,
We are unable to share our source code.
If you would like to proceed, you would need to develop your own SMPP application that can accept all incoming messages. Please note that this may cause conflicts with other SMS services, and we cannot guarantee that it will function correctly in such a setup.
As an alternative, you could create a custom script using the API to collect and forward messages. However, please be aware that messages cannot be forwarded directly to an SMPP application.

Thank you - I am happy to develop the SMPP server ( I did a few of them in the past)
Would you be able to provide some additional information such as how to interact with the hardware/bus/whatever is used internally to read and send SMS?
OK, I figured it out. I am using ubus for communication with the GSM stack. I wrote the SMPP server and it works great!
Another question - would it be possible to get into to the phone call? Ideally, I’d like to get to the media and send the inbound call over SIP. Can you provide any guidance how this should be done?
Greetings,
it is impossible to access phone call media or forward inbound calls over SIP on this platform. The device does not expose the voice/media stream via AT commands, API, or other interfaces, so no supported method exists.
Even if it was implemented, the device would not support it.

Justinas
