IP Phones Phones are registered in the network to make call internally but not able to call outside the network. Do I need any Voice Interface?

it depends on what type of circuit you have or you are getting.

• For SIP interface you dont need anything as traffic is delivered as IP
• For PRI/T1/E1 you will need VWIC3 or VWIC2 MFT card
• For POTS lines you will need VIC3-2FXO or VIC3-4FXO

Also, don't forget to ensure you have sufficient number of PVMDs in the router for TDM voice.

Hi

Thanks for your valuable suggestion.

I have got ADSL2 Line for phone connection and broadband service. I have configured cisco 2911 router so that I can use broadband internet through this into my PC. I insttaled cisco VDSL/ADSL CARD as a interface into router. rj11 cable is used to connect cisco router to PSTN line. I insttaled CME  on this router have registered 5 IP phones with this CME. But I cant make call outside the network using my this PSTN phone number.

I thiNK that I need kind of voice interface card to configure dial peers so that I could do call outside the network.

Ho can I khow it is POTS or E1 Sercuit?

Thanks

What VIC  Should I do if there is ISDN line?

[sky_voice]

Hi Anupam,

For ISDN line E1 you can use G2 series router (2911) VWIC3 cards are preferrable.

If you have 2 E1 circuits, then you can go for 2-port Card - VWIC3-2MFT-T1/E1

for 1 circuit use, 1-port Card - VWIC3-2MFT-T1/E1

HTH.

Hello Anupam,

I think you arr confusing the ADSL line with the PSTN line, maybe you are receiving the internet with your analog line so you had have an ADSL card for the internet connection and one card for analog PSTN connection the part number depends on the analog lines that you have for example for two lines the number will be vwic2-2fxo, don't forget buy the PVDM module.

Hi,

Thanks for suggestion. Could I use same ADSL line with PSTN  to connect vwic2-2fxo card using ADSL filters as I am using two card in this router.

Thank You

Yes. On the FXO interface you will need to place an ADSL filter. Note the correct P/N is VIC2-2FXO.

You will also need UC license, and PVDM3 in the router for the voice card to work.
