Cisco 7925g how to install it in the network
Posted on 2012-12-30
Hi.
we have cisco ip telephony consist of cisco call manager version 8 and IP phones extensions
and there is two VLAN one for voice VLAN-50 and Data VLAN-2
phones are taking IP addresses from catalyst 3750 switch and computers taking from another firewall with different IP subnet
Data has different subnet than the voice
i purchased WAP4410N-E access points and i installed it everywhere plus i created separate SSID for voice.
now the issue is that the cordless phones 7925g when i connect to the network through the access point it take IP address from the data gateway not from the 3750 catalyst !!
and even i configure the voice IP address manually it doesnt work at all
and when i configure the data IP address it works but when the cordless phones speak to each others they cannot hear each others
in my case what is the correct procedures and correct setup to setup the cordless in the voice vlan ?

Looks like you don't have a route between the vlans
You should also look into configuring IP Helper to ensure your DHCP server assigns the correct subnet to your phones.

ok
you know what
i configured the access point voice SSID to join the voice VLAN so now the cordless phones thanks god it takes the voice ip addresses like normal extensions
my problem now still cordless phones when they dial each others each one cannot hear speaker voice we keep say Hello Hello

That's a little weird
I guess you have rebooted them
Does the intercom work though?
I'm racking my brain here

no intercom configured
but FYI the extension numbers configured in the cordless phones already configured for normal phone
thats how i need the setup if some one calling you it should ring in your normal phone as well as the cordless
may be this is the reason ??? should i configure separate extensions and try it out ? or it doesnt make diff ?

I don't have a 7925G phone to test right now.
I would say focus on why the RTP connection between wireless phones are not working. I will research on this too to find out why, if the DNs are truly shared lines.

you know i think the access point am using doesnt transfer RTP signals
i think i have to buy Aironet

That is a possibility though.
On a second thought, the phone works between a land phone and the wireless so RTP tunnel must have been created for voice transfer which would mean the RTP traffic traverses wirelessly. Maybe a wireshark capture can reveal some good info.

power save mode
we are off today .. u know !! i will try something tomorrow
i will configure another access point , so i will have two access points and for each access point i will assign wireless phone and i will try to make a call .. i think it work because i think once wire connection appear in between it work fine
also i contacted the vendor he has to involve his cisco guys to check it

Try using CAM instead of power-save. If you enable power-save the AP must do Proxy-ARP (and I don't think the 4400 does).
Finally it works ooohhh :)
i think 4400 doesnt transfer RTP directly between phones so i made each phone use one 4400 by that way i forced the signals to go through wires and finally it works
but the only problem that with each device i have to assign one 4400 :(
