G.729 is a high complexity algorithm, and G.729A (also known as G.729 Annex-A) is a medium complexity variant of G.729 with slightly lower voice quality. All platforms that support G.729 also support G.729A.
Understanding Codecs: Complexity, Hardware Support, MOS, and Negotiation
We had a fault recently where we had the recording format as G729a and the advertising codec as G729 which was causing garbled messages. The only quick fix was to change the recording codec to G711 - this obviously must be less intensive than transcoding from G729 to G729a and vice versa - although G711 uses up roughly 2.5 times more disk space.
SIP traces provide key information in troubleshooting SIP Trunks, SIP
endpoints and other SIP related issues. Even though these traces are in
clear text, these texts can be gibberish unless you understand fully
what they mean. This document attempts to br...

CUCM Database Replication is an area in which Cisco customers and
partners have asked for more in-depth training in being able to properly
assess a replication problem and potentially resolve an issue without
involving TAC. This document discusses the bas...
