We use this functionality quite a lot in Linphone, although we don't call within a local LAN much so the comments by Stuart are probably valid in your scenario regarding IPv6. just three comments on this: 1) We put the prefix "sip:user@:" in front of the IP address (e.g. sip:[email protected]). It seems to help Linphone know this isn't a phone number but a URI. 2) We've published a free "reduced feature set" version of Linphone for iOS and Android that might help you (assuming you don't need video). It's designed specifically to call without registration. If you simply key in an IP address it will complete the URI for you before making the call. It also keeps its own phone book, aside from the phone's main contact list. Search for "fieldtap" on the app stores. 3) It's entirely possible that if the receive side is registered, invites from destinations other than the registrar may be rejected.
