[OpenSIPS-Users] Protocol/port mismatch warning (TLS - UDP)

[Bogdan-Andrei Iancu]

Hi Matt,

The RURI you receive from the UAC side, does it contain a SIPS schema or 
a "transport=tls" indication ?

The error you see translates into "there is a conflict between the 
requests protocol and the interface you force". So even if you force the 
UDP interface, maybe the RURI may force the TLS protocol, leading to an 
internal conflict.
