IP Phones with DHCP Server in Packet Tracer ?

huud

Hi,

 

I'm configuring this network with IP Phones (I have NOT done IP Phones before) in Packet Tracer 6.2, I have already done enough research on it without any result, the videos that I see have connected PC to Phone and then Phone to Switch and segregated VLANS and configured DHCP pools in the router, I'm using DHCP server rather than the router, unsure if its possible like that.

 

So far what ever I have done of IP Phones is through videos but I'm running into issues.

 

The phones won't ring each other, I only see Configuring CM List.

 

My set up is such that I have IP phones separate from PCs.

 

When I tried to manually enter MAC address then too it would still show Configuring CM List in the GUI window of phone.

 

Scratching my head over what needs be done to make them ring each other.

Hi,

 

Please find the lab attached.

 

Thank You

Hi,

DHCP option 150 is compulsory for Cisco VOIP services and you are missing the same. So Your IP Phones are not getting an IP address from the DHCP Server.

An Example for DHCP Services configuration for IP-Phones :

 

RouterA(config)#ip dhcp pool VOICE

RouterA(dhcp-config)#network 192.168.10.0 255.255.255.0

RouterA(dhcp-config)#default-router 192.168.10.1

RouterA(dhcp-config)#option 150 ip 192.168.10.1 #Mandatory for voip configuration. 

 

 

Reconfigure a DHCP service for the Phones.

Hi,

 

Thanks, from your reply I understand, its not possible to have phones ring each other without DHCP set up  on router.

 

Much appreciated your clarification.

 

Thank You
