Comment #8 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
Do you mean that ProxyImpl#proxyTo should check scheme URI of top Route header (if present) and only if such header is missing it should check request URI? If so, it should work for us.
As for the ALLOWED_ADDRESS_SCHEME, I do not actually see difference between, for example, "tel" scheme and "urn" scheme. "tel" is non-routable as well. So, what exactly does ALLOWED_ADDRESS_SCHEME list mean in that case?
