Re: Error in H.248.41 IP Realm Availability package definition?

Hello Charlie,  cc: Arturo,

Yes it appears that you are correct the available realms property in the 
ipra package does cause a conflict. It either should be binary ID 0x0002 
or the package extension should be removed in order to address the 
issue. Ericsson was the original editor of this work item. This 
Recommendation is also used by Tispan/3GPP so we would need to consider 
this when deciding on a path to take.

Removing the extension is probably the safest path to take. Any other 
opinions?

Regards, Christian
