Re: [reSIProcate-users] Sending on particular transport

[Scott Godin <sgodin@xxxxxxxxxxxxxxx>]

The Contact header is not used for transport selection.  It is typically automatically filled in the stack based on which transport a particular request was sent on.  You can override the stack from filling out the contact header by using SetOverrideHostPort.  If you add the custom parameter ;addTransport to your OverrideHostAndPort then the stack will fill in the transport parameter for you appropriately (ie. if transport is not UDP, it will remove the ;addTransport parameter and add a ;tranpsort= parameter).

In the end I set the transport on the Outbound proxy to TCP, this works. However

I use SetOverrideHostPort on the contact and the transport=tcp param does not

get added to the contact. If I don't use SetOverrideHostPort it does get added.

So how do I add the transport param to the contact when using SetOverrideHostPort

Thanks

Having read through some posts it seems the easiest way is to add TCP to the transport

type of the Via header, but how can I add this so it is added to all outgoing requests

so the transport selector can see this. Using a decorator is too late.

If DNS overrides this I am not too worried but at least it should be the preferred transport to use

if specified in the Via header

You can have a look at this thread:
http://list.resiprocate.org/archive/resiprocate-devel/msg07937.html

I've never tested it, but you could try having 'transport=tcp' in the
Uri passed to setForceTarget. You can also configure a DUM outbound
proxy and put the transport parameter in there, which I've used in the
past (however, this will force all messages to go to that URI).

Hope this helps,
Francis
