[OpenSIPS-Users] smpp manipulation of A and B number.

[Răzvan Crainea]

Hi, Johan!

Yes, the modules do not see the uac_change_from/to() changes - these 
changes only reflect in the message sent downstream.
Therefore, the only way to sort this out is to "loop" the message back 
to OpenSIPS, after the normalization. To do that, after using 
uac_replace_from/to(), you can send the message back to OpenSIPS using:

$dd = "OWN_SIP_IP";

And then "catch" this message as soon as possible in your script and 
send it to the SMPP, using something like:

if (is_method("MESSAGE") && $si == "OWN_SIP_IP")
	send_smpp_message("SMPP");

Hope this helps.

Best regards,
Răzvan
