One of the users has cisco phone and analog phone line connection at his home. He wants to use cisco IP phone instead of analog, how could he achieve this?

Thank you in advance

Does the phone talk back to a CUCM or 3rd party call manager?  

[Syed]

No, there will not be connectivity between his home phone and cucm, but it is exclusively for his personal use.

What model of phone will this individual be using? 

This can be done.  I've posted a lot of responses regarding Cisco phones and Asterisk in this forum. 

[Syed]

Probably 7945 or 7911.

Could you help me with those reference, please?

Could you help me with those reference, please?

No, you must provide the information first. 

1.  Does the person have a voice service provider yet or not? 

2.  Will this voice service provide support Cisco phones? 

3.  Will the voice service provider support ALG? 

4.  Will the voice service provider support NAT?

[Syed]

What does ALG stand for?

[Leo Laohoo]

What does ALG stand for?

SIP ALG

Leo,

Please find the question from user below?

I have only 1 PSTN Analog line from STC (saudi arabia service provider), Panasonic regular phone to connect.

However  is there a translator device such as ATA which  can allow to receive and place calls  from a cisco ?

Syed, 

Let me explain this as simple as I can.  Now I don't know what service STC provides, but one needs an internet service provider (ISP) to be able to surf the internet.  Yes? 

If one wants to connect an VoIP phone up for digital communication, then one must need a voice service provider (VSP).    There are two methods how this can be achieve: 

1.  The phone can, independently, talk to the VSP (via the DSL modem); or

2.  The phone can talk to an Asterisk server and the Asterisk server talks to the VSP. 

However  is there a translator device such as ATA which  can allow to receive and place calls  from a cisco ?

There are several ATA that converts analogue to IP.  Cisco ATA 121/122 is a good example.
