Analog phone via built-in FXS port?

Hello,

We currently have a Cisco CallManager Express implementataion with a 2811 router, 4 built-in FXS and 4 FXO ports, and (5) 7960 IP phones. We would like to use a standard cordless phone for manager only usage early in the morning.

We connected the phone to the first FXS port and are able to dial out and make calls properly as per the dial-peers that are already configured. We would like to configure this FXS port so this analog phone could function similar to an IP phone (answering incoming calls, possibly transfer and on-hold functions).

I've read the CCME admin guide and the guide on voice ports, but I'm having trouble with the solution. I understand that it needs to be configured as an ephone, but how do I configure the ephone to point to the FXS port? Or am I way off base?

Thanks in advance!

Re: Analog phone via built-in FXS port?

You do not need any ephone config. Just define a POTS peer with the DN you wish to associate with the analog phone.

dial-peer voice 10 POTS

destination-pattern 5555

port X/X/X

Re: Analog phone via built-in FXS port?

Ok, so I already have this on my FXO ports:

voice-port 0/0/0

supervisory disconnect anytone

connection plar opx 150

description FXO-xxx-xxx-xxxx

station-id name Outside Line

!

voice-port 0/0/1

supervisory disconnect anytone

connection plar opx 151

description FXO-xxx-xxx-xxxx

station-id name Outside Line

!

voice-port 0/0/2

supervisory disconnect anytone

connection plar opx 152

description FXO-xxx-xxx-xxxx

station-id name Outside Line

And this as a dial-peer for my FXS port:

dial-peer voice 400 pots

description Cordless Phone

destination-pattern 160

port 0/1/0

I would remove that and make a dial-peer such as this:

dial-peer voice 400 pots

description Cordless Phone

destination-pattern 150

port 0/1/0

And any calls coming in on my first FXO port would also ring my analog phone on the first FXS port? (allowing someone to answer using the analog cordless phone if they are not near an IP phone)

Is that correct? Or, does the destination-pattern just signify the extension number of the phone on the FXS port?

Thanks for all the help by the way!

Re: Analog phone via built-in FXS port?

The destination pattern will route calls with that called number to the associated port. So a call to 160 will ring the analog phone on port 0/1/0.

You can't have the FXS port and IP phone with the same extension. Would it work to have the IP phone RNA to the FXS? Or can the user forward the IP phone to the analog phone extension?

Re: Analog phone via built-in FXS port?

So the IP phones can all have extension 150 and are allowed to answer that extension if ringing...but the FXS cannot have the extension assigned? Would the answer be to obtain an ATA-186 and use that instead of an FXS to provide an analog phone?

Here is a sanitized config from the router:

Re: Analog phone via built-in FXS port?

I'm not sure where everyone is going wth this but you CAN use the FXS ports on the 28xx router as an ephone. This is a very nice feature because you get all the ephone functionality on an analog phone such as CFNA, CFB, 3-party conf, pickup groups, transfer, night mode, MOH, etc.

You will need to run the latest 12.4(4)XC IOS and see the following URL:
