I have uc320w with 2.3.2 (6) firmware and 2x SPA504g, 1x 508g, 1xspa303, 1 annalog phone @ fxs port. Both 504g are conected via wifi module. All phones are asign and work well in PBX system and ansfering all external calls even tranfers works well. Only internal dialing and internal conference calls doesn't work, phones ring, but audio not, or just hear myself. Whe is an issue?
You mentioned that both SPA504G phones are connected via wifi. No way audio for internal calls happens between any phones? Or it only happens between these 2 SPA504G phones? What kind of wifi module are you using? Is there any switch in the topology? If yes, what kind of switch? Do you use FXO or SIP trunk for your external calls? Is there any WAN connection for the UC320W?
Yes they have cisco wireless-N bridge for phone adapters. Right no way audio between any phones, even ones they have no more the 10ft of cat5e utp. there is no swich at all, they are are conected directly to the uc320w and have own power adapters. For external calls is used SIP trunk only. WAN connection is direct to provider passing cisco DPC3825 cable modem in bridge mode (SHAW canada) with static IP address. Uc320w is used to route only voice and has WAN connection 50Mbit down and 5Mbit up, 711u is used for SIP trunks. Ping to SIP provider server is around 12ms. SIP is one line(one number) with 4 DIDs
Could you please check if the IP phones are within voice VLAN IP addresses? If your voice VLAN IP is 10.1.1.1, then IP phone IP addresses should be 10.1.1.x. You can check it at Status->DHCP Clients.
If their IP addresses are within voice VLAN, then please collect TCP DUMP at voice VLAN when making an internal call. You can do so at Status->Support Tools->TCP Dump. Please send it to me at firstname.lastname@example.org.
