The format of the SIP INFO message is:
http://www.voip-info.org/wiki/index.php?page=SIP+Info+DTMF
The xml snippet I attempted to use is:
<send retrans="500">
<![CDATA[
INFO sip:[EMAIL PROTECTED]:[remote_port] SIP/2.0
Via: SIP/2.0/[transport] [local_ip]:[local_port]
From: [field0]
<sip:[EMAIL PROTECTED]:[local_port]>;tag=[pid]SIPpTag09[call_number]
To: sut <sip:[EMAIL PROTECTED]:[remote_port]>[peer_tag_param]
Call-ID: [call_id]
CSeq: 5 INFO
Content-Length: 24
Content-Type: application/dtmf-relay
Signal=2
Duration=160
]]>
</send>
My sipp exits/aborts when it reaches that location of the script.
Angelo.

Subject: Re: [Sipp-users] Sending DTMF Digits using SIP INFO
I do not know how to send DTMF digits with an INFO message, but if it is
just a SIP header or body, then SIPp will support it providing you write a
custom XML script.
If you need to do out-of-band RTP signaling it may be possible as well,
but others will have to speak to that.
