2194	small bug in SIP Via header generation	antoine	washort	"There is a small bug in the Via.toString() method. Perhaps it can only occur in theoretical conditions (I don't know enough about the SIP protocol to know for sure).

However, here it is:
{{{
>>> from twisted.protocols import sip
>>> via = sip.Via(""localhost"", ttl=2)
>>> via.toString()
'SIP/2.0/UDP localhost:5060;ttl=2'
>>> via = sip.Via(""localhost"", ttl=1)
>>> via.toString()
'SIP/2.0/UDP localhost:5060;ttl'
}}}

As you see, if a value is exactly 1, it isn't output. This is because of the test ""{{{if value == True}}}"" at line 207. Replacing it with ""{{{if value is True}}}"" fixes the bug.
