We have recently run into a situation where we have run out of room on our head office LAN (/24 Network) and have decided to separate our PCs/Phones at head office onto their own VLAN to give our servers more breathing room. I have configured the Switches,etc and am able to navigate across the VLANs from both sides perfectly fine. My Problem is our VoIP Phones are not sending/receiving any Audio
The Setup is as Follows. we have a pair of Checkpoint Appliances connected in Failover to a Cisco SG300-20 (Set up in L3 Mode). Connected to the SG300-20 are a Pair of HP ProCurve 2520G PoE Switches (To Provide Power to our Nortel iP2002 Phones) and also connected is a 3COM 4200G-48 which is the switch for most of the servers to connect to.
The Checkpoint appliances have been set up with VLAN1 (10.0.20.1/24) and VLAN2 (10.0.21.1/24)
The Cisco has been set up with VLAN1 and VLAN2 and the Ports configured appropriately:
-Ports going to the HPs are VLAN1 Tagged, VLAN2 untagged, and all other ports are VLAN 1 Untagged, VLan 2, Tagged
-PVID on Ports to the HPs are 2 and PVID on all others is 1
The HP's are setup with VLAN1 and VLAN2, and are configured VLAN1 Tagged, VLAN2 Untagged
The DHCP Server resides behind the 3COM and has been set up to hand out addresses in the 10.0.20.x block for traffic from VLAN1, and 10.0.21.x for VLAN2.
The Phone System is a Nortel BCM, with LAN1 behind the 3COM (With a 10.0.20.x address) and LAN2 in one of the HPs with a 10.0.21.x Address)
PCs/Phones now in VLAN2 are picking up DHCP Addresses for VLAN2 from the DHCP Server correctly, are able to navigate across both networks, and out to the internet as well.
The Phones are finding DHCP, and are using a manual Setup of S1 and S2 on the phones to locate the BCM.
I have tried using both the IP of the BCM in VLAN1 and VLAN2, and the phone boots, connects to S1 and loads. The Phone will ring, show voice mails, allow outbound calls, but you are unable to hear the user on the other end, and vice versa.
The One thing I have noticed is when I look at the phone in BCM Element Manager, it thinks the phone has been assigned the address of the default Gateway in VLAN1, and not the correct address in VLAN2. I am at a loss of where to go from here.
Any suggestions??
