Hi,
Two remarks:
1) the path taken by a request will be taken (in the opposite direction)
by all the replies of that request - that is SIP :) . So, if your INVITE
went through the dispatcher, all its replies (180, 200) will go via
dispatcher
2) for sequential requests (ACK, re-INVITEs, BYEs) you can make them
skip the dispatcher by NOT doing record-routing on the dispatcher for
the original INVITE
1') regarding my comment from 1) - you may play with the send() function
- this is a stateless function for sending a request out but without
adding any VIA in the request. So the hop doing send() will be invisible
for the replies also (the replies will bypass this hop as there is no
VIA for it) - but I warn you that this is against RFC3261 and also it
might generate problems at network level (a SIP point expects to have
the same IP:port peer during a transaction)
Regards,
Bogdan
