  • SIP registration works with or without authentication.
  • Basic call works as long as the E60 gets an SDP offer with the initial INVITE. "Late offer/answer" does not work with E60. In result multiple registration will not work with the E60.
  • Re-negotiation (e.g. after call transfer) does not work at all with the E60.

Conclusion

The E60 does not support the basic offer/answer model for media negotiation (according to RFC-3261) and is therefore not interoperable. Future software upgrades for E60 may improve things.
