Got an ITSP who sent me instructions, sip trunking, static ip authentication, with the sip signaling on a different host than the media.

sipx 4.2.0.

first test call was an inbound call from itsp1 to a DID that has call fwd no answer, call is fwded to a number that matches a dial plan that is on itsp2,
(itsp1 uses same ip for sip signaling as well as media)
itsp2 is the one with the split sip.. of course, I have never heard of this.

obviously, the call never completed, not completely.

caller heard ringing, and then 'at the tone, please leave a message'.
but, the external cell phone saw the call coming in.

wireshark shows INBOUND audio from itsp2.s media server, but there is no outbound rtp to that server (call is an almost answer)

not sure if the split ip (.1 is signaling, .2 is media server) is supported.
