Make sure the file sipra.properties, located under $PROJECT_HOME/ra/sipra/ra/src/org/mobicents/slee/resource/sip/, contains the correct information, for example:
# Default IP address 0.0.0.0 can pickup the IP address
# automatically -- this is not a good idea if you have
# multiple interfaces.
#
# When javax.sip.IP_ADDRESS is not specified, the SIP RA
# uses the default binding address of the SLEE container
#
#javax.sip.IP_ADDRESS=127.0.0.1
