[azamated]

Hi everybody,
I have OXE rel. 9.1 patch 37a

we want to implement sip trunk to sip trunk transit. And we 've got broblem with RTP flow. It is flowing directly , not through PBX.

How to switch on RTP proxy feature??

Thanks

There are 3 devices : PABX_Motorola -(sip trunk) - ALU- OXE - (sip trunk) - Sip provider

When PABX Motorolla trys to call outside the SIP signalling is going theough ALU, but RTP is going directly from Motorola to SIP provider. But threre is a difficulties with network and NAT to all this scenario.
So I need that ALU to proxy RTP traffic as well

I'm not pretty sure, but since R9.0, the direct RTP is disabled for some boards.

very strange system...

Try IP parameters--> Direct RTP --> false
You may need to restart INTIP board.

There's no global value IP parameters--> Direct RTP --> false - there are only "Direct RTP For H323 Terminals".. And what one can do with SIP-trunks media, when You need to create SIP-trunk with no direct media??? Is there any way out? In my case i have crystal based media gateway.
My OXE is R11.1-l1.301-35-a

Not possible. Check the date!!! This is not available anymore.
I guess you can force the trunk through an SBC...I know direct RTP through SIP is a real problem for firewall configuration...
