Cisco Wireless Bridge and IP Phones

Hello to all.

I would like to ask a question. I am new to commercial wireless access points (Cisco and such). I have a new client that has 2 Buildings across the street from each other. This client is in a small farming community out in the middle of nowhere. Their original configuration had the two building networks connect thru the ISP utilizing a VPNand 2 public IP Addresses. The equipment for each side was a Netgear VPN/Firewall/Router which required each building to be on a different subnet (192.168.1.0 and 192.168.2.0). The Netgear boxes completed the Level 3 protocols and thus each side could talk to each other.

Over the past few years the ISP pipe for this connection has degraded to the point that a 5Mb pipe is only letting 1Mb through. The ISP is not willing to fix their equipment at this point. This being said the client purchased 2 Cisco 1572 Access Point which we configured to act as a root/non-root bridge. Once the bridge was connected we then went to put everything onto a single subnet (192.168.1.0).

The only issue is their phone system. The client is using a Samsung Officeserv 7100 to provide VoIP communications to both buildings. We went into the Samsung phone system and changed the IP, Gateway, and restarted the MP10 card. At this point the phones in the building where the main Samsung unit is housed work fine but the remote phones across the street can call out but can’t be called into. We put the phone system back on the old connection it works fine.

I have checked the old routers and can’t seem to find anything specific in the configuration to allow or disallow the VoIP traffic and I have always though that VoIP traffic is no different than regular network traffic.  

So my question is does something specifically have to be done to allow the VoIP traffic over the wireless bridge? I appreciate everyone help. Thanks

Did you re-provision your phones on the 192.168.2.x network, or did you just plug them in and hope they'd work?

If your subnet is wide enough, .2 can communicate with .1 and your phones could have the correct PBX for outbound communication, but when you get an inbound, the pbx is trying to reach the phone on it's old .2 address..  Make sense?

I guess I am not understanding. We changed all the IP Addresses on the devices that were on the 192.168.2.0 to 192.168.1.0. Everything came up except for the phones. I assumed that since the remote phone would pull new IP information when the system rebooted. I understand that the phones while configured on the original setup would receive information that's origin was the 192.168.2.0 network and send it back the same way. But when the system rebooted shouldn't they get the new configs since everything is on the same subnet? Thanks
