We have a 3 MB MPLS connection to a new site. Cisco Call Manager servers are at another site on the other side of the WAN. We have some questions on the QoS configuration. Our local router is a 3845, the far end is also a 3845.
The 2 T-1's are bundled with MLPPP. Once a call is established, does the established audio stream go across: a) the âbundleâ or b) one of the T-1's?
If it goes across one the T-1's, could the packets go back and forth between the 2 T-1's? Our network team has recounted to me that when voice traffic was going down BOTH the ISP "A" DS3 and the AT&T MPLS DS3 at a larger site, voice quality suffered. Once it was directed down one path or the other, voice quality is fine.
Our other engineers were thinking that we should unbundle the 3MB and use PBR to direct voice down one T1 or the other.
What does this group think?
