Hi Kpirlo,
When sending the call to the dip provider, use a failure route in order
to catch the 3xx reply you get back. In the failure route, use the
uac_redirect module with the get_redirects() function
(http://www.opensips.org/html/docs/modules/1.7.x/uac_redirect.html#id250367)
in order to extract the redirect contacts from the reply and push them
as new destinations.
Regards,
Bogdan

We are currently using the Dynamic routing module for our least cost
routing.
Now we are looking at implementing an LRN dipping service, where we
will send the call to a dip provider first and receive a 302 redirect
back which will have the LRN returned in the contact header as "rn="
if the number has been ported or will include ";npdi" in the contact
header if it has not been ported.
Im asking for any advice anyone has on how to implement this and how
it could work with dymanic routing to choose the route based on rn if
available, but actually send the call using the original "to" number.
Thank you in advance for any help.
Kent
