I am getting these warnings when the modules are loaded :

 [chan_oss.so] => (OSS Console Channel Driver)
WARNING[16384]: File chan_oss.c, Line 974 (load_module): XXX I don't 
work right with non-full duplex sound cards XXX
  == Registered channel type 'Console' (OSS Console Channel Driver)
  == Parsing '/etc/asterisk/oss.conf': Found

 [chan_modem_bestdata.so]WARNING[98311]: File chan_oss.c, Line 232 
(sound_thread): Read error on sound device: Resource temporarily 

I am getting a segmentation fault once the call is established between 
SIP endpoint ATA 186 and H323 end point ATA 186.

The  gdb is as follows:

Program received signal SIGSEGV, Segmentation fault.
