Architectural Details

Fundamental architectural difference between SIP proxy vs. B2BUA

B2BUA more feature-rich functionally enhanced (intelligent codec semedia control, etc.)

SIP proxy less functional higher scalability based on limited signallin

SIP proxy doesnt provide advanced media services, i.e., music on h

Media Bypass requires a common IP address for signalling and media (optional 2 IP adsignalling and one for media)

For all media traffic to come from a single IP address a Media Termination Point (MTP)

Load sharing on multiple MTPs not supported (single IP address for media)

Each node in CUCM cluster has to be defined in Lync as Gateway, other common met(DNS FQDN or SRV) would break the requirements of Media Bypass for IP addressingsharing via Route-List and Route-Group

Considerations

Co-Location of Mediation Server only with Media Bypass and if EVoice not mission critical

Media Bypass mandatory requirements still cause hair pinning of

Media Bypass does not allow for utilisation of distributed media r(MTP)

Media Bypass only recommended for local (LAN) interoperability PBX or Gateway. Significant caveats in centralised call controldeployments

Media Bypass forces G.711 only sub-optimal for low bandwidthenvironments, no wide band capabilities. Further requiring a transdevice to support other standard codecs such as G.729, G.726, iiSAC, etc.
