Are we sure that a 1xx response has been sent to the ISP within 32 seconds? According to the flowchart on page 128 of RFC 3261, the callee has "Timer B" time to send a 1xx response or the caller can consider the call timed-out. According to the table on page 265, the default Timer B value is 32 seconds.
