[Serusers] To and From Headers - Angle Brackets Or Not

[Java Rockx]

Hi All.

I'm using ser-0.9.1.

Does anyone know if angle brackets are required around the TO: and
FROM: headers?

Our Sonus gateway sometimes omits these brackets and I just want to
make sure that SER correctly identifies SIP transactions.

Here is a PSTN->SIP INVITE that shows the brackets being omitted.
