Summary:                    Memory segmentation fault on T.38 pass through
Description: 
I tried to use the chan_sip with T.38 pass through. An Fax is coming via
T.38 from
the Carrier an should go to a Linksys SPA2102 (T.38 enabled).
Short after starting UDPL traffic I got a segmentation fault.
The crash is 100% reproducible.
Outbound T.38 is no problem at all.

  Fix crashes when receiving certain T.38 packets.  Also, increase the
maximum
  size of T.38 packets and warn users when they try to set the limits
above those
  maximums.
