BCM 400 Cannot hear

[whender]

I have a BCM 400. Cannot hear conversion on other wide and they cannot hear me. I2001 sets. Phone on other sides got new set messages and password. Sets ring each other. Opened ports 7000 28000-28255 and 51000-51200. Any ideas?

Thanks

Sounds like both sets can route to the bcm, but not each other. Check your gateways in the phones. Need more info on the network.

I have Comcast Cable and a Dlink DI524 router. I am attempting to connect to a phone over the internet not attached to a BCM. I have port forwarded 7000 to my BCM which intern gets it DHCP from the Dlink DI524. Address on Lan port 1 on bcm on different net. 10.10.10.1 lan 2 192.168.0.200 di524 192.168.0.1 28000-28255 51000-51200 allowed from wan any protocl forwarded to 192.168.0.200.

Any idesa?

The signalling is done between the ip phone and the BCM, even for two IP phones ringing each other.

However, when two IP phones have a conversation, the audio packets are sent directly between the phones (not through the BCM) even though the signalling goes through the BCM.

So, with wrong routing/gateways set up, the IP phones can ring each other (and talk to digital phones no problem) but no audio will work or you can get one-way audio.

Can you tell us the IP address, subnet mask and default gateway on each IP phone?
Are they at the same location or different locations?
