Re: [reSIProcate-users] Forcing an Outbound Transport-Type

[Gabriel Hege <" gabriel-mailinglists"@gmx.de>]

Hi Scott,

thanks for the quick reply.

Stepping through the code (resiprocate version 1.7.1) I found the 
problem in findTransportByVia(), but the respective code has not changed 
in trunk.

The problem is findTransportByVia() sets the transport type in the 
source tuple, to the transport type found in the target. I think if a 
Via is present with the transport set, this should be used.

I will try to provide a patch.

Best regards,
 Gabriel
