Hi, I've been interacting with Teltonika's SMPP implementation but up to now I've only got to send simple SMS (submit_sm). I tried to use other ops like bind_transceiver, bind_receiver and submit_multi but to these ones the server respond me with a generic nack with an 'unknown error' even though Wireshark confirms that the package I've sent is correct.
I'm not quite sure if the matter is that Teltonika's SMPP implementation hasn't those operations or there's something missing. Anyone has used those operations before in Teltonika's modem? or do you know that they aren't implemented?
Thanks for the help
