Configure MTP2 in Yate

The MTP2 link is created on demand. To define a MTP2 link you must define the MTP3 linkset that uses it.

In ysigchan.conf:

[mtp3]
type=ss7-mtp3
netind2pctype=ITU
netindicator=national
local=ITU,0-0-6
adjacent=ITU,0-0-5
link=mtp2

[mtp2]
type=ss7-mtp2
autostart=yes
emergency=yes
autoemergency=yes
sig=wanpipe1
filllink=no

Note: According to standards filllink should be 'yes'. We usually set it to 'no' because most of the times the underlying layers don't have support for it (unless when support was added in the hardware and then it's ok to configure filllink='yes').

In wpcard.conf

[wanpipe1]
type=E1
siggroup=w1g1
voicegroup=w1g2

+This is a short example on how to configure MTP2 in Yate.
-MTP2 implementation in YATE is located in ysig library. The methods declaration is in libs/ysig/yatesig.h and the implementation in libs/ysig/layer2.cpp. Class name is SS7MTP2.
