around with Cisco SLB where the sip gateway forwards the sip packet to the SLB

the SIP headers aren't being correctly modified and I'm about to give up on
doing it this way. </SPAN></FONT></DIV>

then forward the sip packet onto one of the two CCM's??</SPAN></FONT></DIV>

Cisco Call Manager 5.1 servers here and need to integrate this with our
current SIP set up which uses PortaBilling. When external calls come into our
SIP gateway (PortaBilling), they are forwarded to the Cisco Call Managers (CCM).
Because we have TWO CCM's (for redundancy), PortaBilling forwards it to both
Call Mananger Server and we end up with two calls showing up on our Cisco IP
Phone PLUS it takes up two media (dsp) channels. </SPAN><o:p></o:p></P></DIV>

that can be done from either Porta or on the Cisco Call Manager to prevent
