<DIV><FONT face=Arial>Hi, Moises, </FONT><FONT face=Arial> </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial>As you suggested, I have completed the ISUP<->SIP-T
conversion work. While there are some problems to integrate my code to
freeswitch.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>1. I got one sangoma license and can bridge the
freetmd to sofia now. But how can I intercept the ISUP mesasge(from the
freetdm) and run to my application and then to Sofia module? Is there any
external control like ESL to do the work? The diagram is like:</FONT></DIV>
<DIV><FONT face=Arial> </FONT></DIV>

ISUP</FONT></DIV>
<DIV><FONT

SofiaModule<-------------My
Conversion---------------------->freetdm</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>2. I have been working with ESL "SEND" command to
control the Sofia module, while it needs to divide the conversion SIP-T message.
Is there anyway to put the one whole SIP-T message to Sofia module to handle?
like one external SIP-T message to freeswitch?</FONT></DIV>
<DIV><FONT face=Arial>And vice versa, Is there good way to receive the whole SIP
message from sofia module instead of using ESL to detect the SIP message
info?</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Appreciated your comments.</FONT></DIV>

studying freeswitch for a few weeks. I will be planning to take the
freeswitch as a signal gateway connecting PSTN(ISUP) and SIP.<BR>It
needs convert the ISUP to SIP based on RFC3372/RFC3204/RFC3398
and vice versa.<BR>I notice in the mime_type.cfg supporting
applicaiton/ISUP, but I don't find any code in sofia(SIP) module to
decode/encode the application/ISUP.<BR>My question is: Does freeswitch
support to do the signalling gateway connecting ISUP(freeTDM module
also has the MTP layer support) and SIP(SIP-T/SIP-I)? If yes, could
you let me know how it works?<BR><BR></BLOCKQUOTE>
<DIV><BR></DIV>
<DIV>Hello Windy,</DIV>
<DIV><BR></DIV>
<DIV>There is no support in FreeSWITCH for SIP-I or SIP-T</DIV>
<DIV><BR></DIV>
<DIV>ISUP to SIP conversion is supported using Sangoma's SS7 module
based on Trillium SS7 stack. Note this is licensed, not open source
(this is true for all the MTP layers and ISUP, SCCP etc).</DIV>
<DIV><BR></DIV>
<DIV>Sangoma uses a raw/proprietary mechanism to pass-thru complete IAM
messages in a SIP network, it is a crude embedding of the IAM message
encoded using base64, within SIP header. We are aware this is crude and
by far does not cover all cases, but it was done as quick and dirty way
to avoid implementing the whole SIP-I/SIP-T spec and at the same time
not miss any IAM information. </DIV>
<DIV><BR></DIV>
<DIV>In all honesty we've had not seen many requests for it so that has
kept us from doing the implementation work.</DIV>
<DIV><BR></DIV>
<DIV>Cheers,</DIV>
