Flowroute on IP500v2 R11.0.4.7 One-way audio

[telfire]

Everything has been working fine with this customer for months. Suddenly overnight, I start getting one-way audio on inbound calls only (outbound works fine with 2-way audio).

Under LAN1>Network Topology, I have set to Unknown, refresh at 30 secs, The public IP address set and 5060 for UDP and TCP.
On the SIP trunk, for Local Domain I have the public IP address, transport is us-east-va.sip.flowroute.com

Flowroute is claiming that because I am sending "c=IN IP4 10.0.0.250" that is the reason and they are apparently sending the RTP to the private address.

I am not in a position right now to switch carriers although I am making steps to do so after this is cleared up as they never accept blame nor attempt to fix anything on their side.

Any input would be appreciated.

Flowroute has been the one of the easiest setup I've ever used, so I'm surprised you're having issues with it.
There shouldn't be any "public ip address" on the sip trunk. the ITSP should just be the flowroute address, no need for the proxy.

Set your firewall to static port blocking if you're just doing basic port forwarding.

If they are seeing the Private IP address in the header & not your public IP address then you have not configured your network settings correctly, 2 options

1) Preferred Solution
Enable SipALG on your router

2) only if Option 1 is not possible
Configure the Lan topology to use a Stun Server

Or better still add an ASBCE as a sip proxy!
