ADSL and SIP

Hi there I am mandatory to use ADSL with it comes internet, IPTV and telephony. The ISP uses PPPoA, so I have to use "something" that can do PPPoA to PPPoE to use pfSense. For this I use the Draytek Vigor 130 as it can bridge PPPoA to PPPoE and it does it really nicely, but how can I get telephone line (SIP) to work.
Anyone any thoughts,
It's replacing some all-in-one ISP device I assume? Probably have to see how that connects the VoIP part. I'd be surprised if there is nothing about that detailed somewhere already. Who are the ISP?

The ISP uses PPPoA
for Internet, right? But what about other services? I guess they may use multiple VPI/VCI pairs to provide various services. Potentially they may use IPoA over some another VPI/VCI pair to provide VoIP, etc. I would start from identifying the VPI/VCI pairs and encapsulation protocols used.
So, the general approach is to bridge each outside ATM connection (identified with VPI/VCI pair) with either a VLAN or a physical port on ADSL modem. The further should be pretty straight forward with any router.

Both thanks for your reply, as I read the ISP forum I came across info that tells the ISP uses vpi/vci 8/48 for internet and vpi/vci 8/71 for IPTV, but I cannot seem to find anything about how they port telephone on this adsl line. The only thing I see in the logs of there all-in-one device is a connection to a SIP email@example.com how can I analyze what vpi/vci this uses or is it just a client in the ISP router that logs in the SIP server? What I have accomplished is
Internet----Draytek vigor 130 modem in PPPoA/PPPoE bridge mode----pfSense
But then I cannot connect my phones. Maybe if I put the ISP-all-in-one router in the LAN of pfSense it maybe connects to the providers SIP and I could then connect my phone to the all-in-one device.

@Qinn, if there is no separate PVC for voice, I would assume that they use Internet connection also for voice, so just try accessing their SIP server with any SIP-client. Even if you don't know your SIP password you should be able to see server response [if it is reachable over this connection]. No relation to pfSense yet.

@AndrewZ I don't know if there is a permanent virtual circuit for voice.
