[reSIProcate] Question about implementing own Transport and Sip Stack Interactions

[Sunitha Beeram]

 Hi,

   We plan to use epoll() for our application and sip
stack fds instead of going the current select() way. I am
assuming that if I implement my own transport this should
be possible. I think I have mapped most of what needs to
be done to implement the Transport interface, so the sip
stack interactions are taken care of - one issue I am not
sure about is the DnsStub object in the stack. Is it
possible to drive that too through our own transport or
do we have to implement an external DNS for it? 

    Does anybody have notes (dos/donts) for implementing
an external Transport? 

Thanks,
Sunitha.
