Hi
I'm implement Cisco C8300 as a CUBE Media Proxy for streaming RTP to 2 recoding servers in the same time
but still not working , I'm found some error when
at first , I just configure follow Cisco Document which are
- Recording profile number route to sip trunk from CUCM to CUBE Media Proxy
- Dial-peer incoming , 2 Dial-peer outgoing to 2 recorders map to medial-class
then I test but not working , I facing issue about SIP invite , that is some attribute in sip header missing, such as attribute "From" in Call Recording Meta-data part ( x-nearend,x-refci.....) we fix it by copy sip invite from incoming dial-peer then modify and map to outgoing dial-peer
after that recording server can receive RTP , but not stable sometimes RTP send to 1 recorder, but sometimes send to both recorders , I debug ccsip message and found 2 case which are
1. send to both , 1st sip invite is normal , the 2nd and 3rd show 500 Server Internal Error

2. send only 1 recorder, 1st sip invite is normal then show 500 error and , no invite to 2nd recorder.
