The following example is unfeasible with a proxy (it requires a B2BUA): - alice calls bob (through the B2BUA). - bob answers and they talk for a while. - After 20 seconds bob hangups. - The B2BUA initiates a new leg to carol. - alice talks with carol. Impossible with a proxy. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
