Hi
I am trying to design a SipP script for UAS with PRACK.
The script receives PRACK & sends 200OK for PRACK & then waits for 10
seconds & then sends 200OK for INVITE. But for some reason 200OK for INVITE
doesn't get ACKnowledged from the UAC.
Any ideas what could be the issue. Does anybody have working scripts for UAS
with PRACK? It would be great help if you could share those.
Script below:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<scenario name="MCP_simulator">
<recv request="INVITE" crlf="true">
</recv>
<send>
