softphones 2050 and reinvite

[heros2007]

Hi all
I have a BCM50 R2 with some softphones 2050
the 300 softphone is on 192.168.1.X subnet
the 301 softphone is on 192.168.0.X subnet
the BCM50 is on 192.168.3.X subnet

each softphone can see BCM50 via the gateway
when 300 calls 301, 301 hear ringing
when 301 answer, no audio can be heard

The problem is that RTP goes directly from the 300-301
and they cannot see each other directly!
Is there a way to tell to BCM to handle the RTP and redirect it to IP phones?

Thank you all!!

No. Media path is always directly between the two IP Phones (hard or soft).

As a remote 2050 user(not same subnet) are you using a contivity client to establish connection to BCM?

Does the audio work when on a call to a TDM set/line? or when all (phones, bcm) are in the same subnet?

 

[heros2007]

I'm not using contivity client. Connection to/from BCM works
because each phone can see the BCM.
I call a TDM line without problems

As i suspected if media path is always between IP phones
that's the problem.

no NAT is allowed between IP phones

Thank you,
Heros

You need to have each IP phone be able to see each other. When connecting IP phones that are on seperate networks, you need to make sure a VPN tunnel is created between the external routers. This will allow the RTP traffic to traverse the network, and you will get your voice traffic to work. This can be done on Cisco PIX devices, or any router that supports VPN.
