Hi, if I understand correctly, mod_fifo works by calling initialy to every agents. Later when an inblund call arrives, FS brigdes such call into an existing call with an agent. This means that the agent's phone uses the same SIP dialog for every inblund call to the queue. So, the agent doesn't know the callerid number of each call. For this, there is a RFC which provides dynamic From header within the same dialog. Of course this requires the phone to support it, but it will occur soon (I hope). The spec is RFC 4916 and basically means that an endpoint of the dialog can send a re-INVITE or UPDATE within an existing dialog containing a different From header. The negociation of this feature is handled by common Supported/Require headers. http://tools.ietf.org/html/rfc4916 Would it be useful to implement such feature in FS? Thanks a lot. -- Iñaki Baz Castillo <ibc@aliax.net>
