We have at least two cases now where an update to the RFC added important MUSTs:
- Tel uri - phone-context is now required, which affects all SIP
devices using SIP uri with user=phone regardless if they use a Tel: URI.
Sincerelly I can't understand the usage/requeriment of "user" parameter. How would detect a phone if the dialed number is a PSTN number or an extension? For example: - 1004 is a short number in Spain (Telefonica) - 2002 could be a domain user
How
I expect that phones don't need to implement all the PSTN dialplan of the world :)
