Long messages get split incorrectly

[tomngo]

Summary

Long messages get split incorrectly by Restcomm.

• Each message has unexpected extra bytes at the start of its text. This part is 100% repeatable.
• Often some pieces are missing. This part is sporadic.

Impact

Every message that long enough to be split into parts is affected.

I believe there is no workaround, but am obviously open to it.

Isolated to Restcomm

I've changed every variable outside of Restcomm, and the behavior is identical:

• The same thing happens when the message is sent from my handset (on T-Mobile) through a Restcomm instance, whether that Restcomm instance is tied to Teli (tom+rcteli@lumin.ai), or to Hook (tom+rchook@lumin.ai).
• The same thing happens when the message is sent from my Google Voice line through a Restcomm instance, whether that Restcomm instance is tied to Teli (tom+rcteli@lumin.ai), or to Hook (tom+rchook@lumin.ai).
• A message carrying an identical string arrives intact if sent from my handset to my Google Voice line without going through Restcomm, or vice versa.
• The corruption is visible in the Restcomm logs, i.e., before reaching our platform.

Examples

Well, wouldn’t you know it. They’ve changed the schedule again. I can do 11/21 at noon.
