Re: [reSIProcate-users] a question about maddr param
in the 18.2.2 Sending Responses of rfc3261 is about response.
i know there is process in DnsResult::lookupInternal,but i don't think
it will pass the DnsResult::lookupInternal when stack send a response.
using dns,not only here as below?
mDnsResult = mController.mTransportSelector.createDnsResult(this);
mWaitingForDnsResult=true;
mController.mTransportSelector.dnsResolve(mDnsResult, sip);
in TransportSelector::dnsResolve function there are:
else if (msg->isResponse())
{
ErrLog(<<"unimplemented response dns");
assert(0);
}
