Sending Double Message in Dialogic Sigtran

The problem of sending 2 or more message once you send 1 message from top of stack pretending to sctp. In new version of host software package(5.05) a new configuration command -CNTOS- is supported to setup timing for sctp and m2pa.

To prevent sending more than one same message the retransmission configuration of both side must be same. In dialogic side it's done by CNTOS command and RMIN(retransmission min) and RMAX(retransmission max) parameters. In cisco itp side can be seen by sh cs7 m3ua command.

Presenting of Point Code in SCCP Called Party

The way to set Present of PC in Called and Calling Party of SCCP layer in dialogic host software is setting ext_options of SCCP_Config command which is 16 MSB of 32bits option parameter.
Presence of PC in CDPA is equal to set bit #2.

SCCP_CONFIG 10278 0x8 0x00020102 0x00000001

Detail of setting these bits is discussed on SCCP Programmers Manual, ext_options section.
