Crack that SIP
Give the past the slip
Step on a crack
Break your asterisk's back
When a call comes along
You must SIP it
Before the invite sits out too long
You must SIP it
When something's going wrong
You must SIP it
now SIP it
into shape
shape it up
get straight
go forward
move ahead
try to detect it
it's not too late
to SIP it
SIP it good
When a good time turns around
You must SIP it
You will never live it down
Unless you SIP it
No one gets their T.38
Until they SIP it
I say SIP it
SIP it good
