Comment #3 on issue 2327 by [email protected]: Mobicents proxyTo fails
when proxying to "urn:service:sos" Request-URI
http://code.google.com/p/mobicents/issues/detail?id=2327
Even though it is possible to add URN to the ALLOWED_ADDRESS_SCHEMES of
JainSipUtils, I am not sure a URN is routable and should be attempted to be
proxied.
According to the RFC5031:
...Since service URNs are not routable, a SIP proxy or user agent has to
translate the service URN into a routable URI for a location-
appropriate service provider, such as a SIP URL. A Location-to-
Service Translation Protocol (LoST) [LOST] is expected to be used as
a resolution system for mapping service URNs to URLs based on
geographic location. ...
So I believe you need to translate URN to a SIP URL before trying to proxy
that request.
If thats not your use case, please correct me.
