Hello, I have a bit of a strange situation where I want to add SIP MESSAGE reliability (store and forward) for a proxy that is in front of the (message-wise unreliable) registrar/message originator. So I m_store MESSAGEs in the failure_route of MESSAGE requests. By default, msilo's m_dump works only for REQUEST_ROUTE, thus I can't use that in the 200 to REGISTER. But when I add a function to msilo for ONREPLY_ROUTE (without the check for MESSAGE support) it works. So, is there a reason that there's m_dump only for REQUEST_ROUTE? And, is this: if ((msg->first_line).type == SIP_REQUEST) the correct way to check whether we're handling a request or reply? Also, is there a way to check the expires of contacts in the 200 to REGISTER from the script, so I don't try to m_dump on de-REGISTER? Or does this have to go into the m_dump function for the ONREPLY_ROUTE case? Many thanks for hints! Stefan
