[Asterisk-Users] Q.931 to SIGTRAN interface

Hi,

In response to:
http://lists.digium.com/pipermail/asterisk-users/2005-March/098214.html

<quote>
How about simply doing a Q.931 to SIGTRAN conversion module.... would
that not be simpler to implement?
</quote>

Implementing this idea would help Asterisk become integrated with SS7 gateways
in a
generalized way.

A first step could reasonably be to implement a Q.931 to UDP connection.
The next step would be to replace UDP with SCTP (now in 2.6 and being
back ported to 2.4). Next would be an effort to implement M3UA/SUA/IUA.
In parallel would be an effort to implement ISUP on Asterisk.

I will contribute SIGTRAN and ISUP code to Asterisk under GPL from my working
repository of those protocols.  There also is a supposedly working M3UA in
Sourceforge whose author still responds to email.

[Asterisk-Users] Q.931 to SIGTRAN interface

Thanks Mike,

	I am getting letters from Europe for doing ISUP first, after the
D-Channel and LDAP are working.

	Another suggestion has been to create Asterisk as an SG for
other asterisk boxes their by taking load off the Asterisk backend farm.

	But I think it should run on a single box for the little guys
too.
	
	The plan is to make the interfaces use sockets to communicate so
that the processes can be migrated off the box if that is needed.

	Remember that Linux can do local host sockets that don't climb
the entire stack so the performance penalty is not that great compared
to the feature set of using sockets.

	If speed of the calls cannot be maintained then it will switch
to a non-socket approach, but the code will hide all that in the
classes.
