[SR-Users] Trouble with rtpproxy

[Igor Potjevlesch]

Hello,

The different rtpproxy_manage work fine.
I have an issue with Record-Route and Via header. Is it possible to change
these headers with the expected IP address on egress sides and keep the IP
address of the proxy for ingress sides?

Regards,

Igor.

Alex,

Thank you. I reviewed the doc this morning and I missed it.
Next step would be to announce a different IP address for the ingress sides
than the egress sides. Is that make sense?
I try to add the target IP address expected by my provider. It works fine,
but in my internal network I hope to see another IP address.
That would mean a different rtpproxy_manage instruction depending on the
branch. But I don't know how to identify those branches.

To illustrate:
Rtpproxy_manage("..."); -> for ingress.
Rtpproxy_manage("...","expected_ip_addresses") -> for egress.

If someone has an idea to do so.

Alternatively I can use a Cisco ASR router between my platform and the
provider. I don't know if I can manipulate SDP with this. The basic NAT
instructions doesn't do this job and the provider seems to keep the IP
address in the SDP.

Regards,

Igor.

Yes. Use the 'r' flag in rtpproxy_*() functions, and do not use the 'w' 
flag.
