Two no's of IP Telephones are not working simultaneously on Express 500

Hi,

We are newly installed Cisco Catalyst Express 500- 24 TT (WS-CE500-24TT)switch using for IP Telephony, I connected two no's of Cisco IP Telephones to switch. Problem is only one IP telephone is working at a time. Both IP Telephones are not working simultaneously what could the reason is any limitation in switch for IP Telephony applications.

The switch configuration everything is default configuration only.

Anybody face this problem please suggest me.

Thanking you,

Regards

Ranga Kishore

Hi

Can you tell me whether you are plugging in only the ip phones or both ip phone and desktop ?

have you already configured the ports on voice vlans so that the voice transmission quality can be taken care ??
