Hello, thank you for your assistance.<br />
<br />
We have two T1's from Location A to B, and a Cisco 1841 Router with a Dual T1 WIC at each location. Our requirement is to have the two T1's bonded into a 3Mbps pipe. If one T1 shall go down, the link should still stay up on the other T1 line.<br />
<br />
Since our phones which are VOIP based, are going to be chatting over this connection I need to make sure that call quality is exceptional and stable. Do I need to use QoS? Should I use MLPPP? <br />
<br />
What is the best way to accomplish this? I am not allowed to change the routers, I must keep the 1841's one at each location. &nbsp;I would really appreciate a concrete example or cisco config as I have not done this before.<br />
<br />
Thank you very much!

How to bond two T1's into a single 3Mb connection point to point with VOIP and Normal Data Traffic QoS

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).
