Description:In our asterisk we have a trunk in Woomera channel to connect by ss7 to our upstream and a PRI interface to connect asterisk to our voip concentrator.

The problem is that asterisk doesn't send a PROGRESSING dss1 messages after the CALL PROCEEDING messages.

This pushes the voip appliance to use 180 instead 183 sip messages and I don't have EARLY MEDIA on the link.

this is my zapata.conf and a call signaling log:
[channels]
context = prova
switchtype = euroisdn
usecallerid = yes
echocancel = no
echocancelwhenbridged = no
relaxdtmf=yes
rxgain = -1.0
txgain = 0.0

signalling = pri_cpe
group =1
channel = 1-15,17-31

;Note: Customers in the UK connected to BT might require this parameter:
callprogress=yes
progzone=it

I contacted also the support dep of the voip box's vendor and they told me the same. If they have progressing messages they have early audio on sip; if they don't they send only 180.

Have you tried using the Progress() application in your dial plan?
