Digium have announced new versions of the G729 codec.
The new modules were built using the latest (4.3) release of the GNU C compiler, and use a number of new optimization methods available in that release to significantly improve encoding/decoding performance. In addition, we now build the modules in both 32-bit and 64-bit varieties for each CPU flavor that support both modes, so that users with 64-bit CPUs running a 32-bit Linux installation can still have a version of the module optimized for their CPU type. GCC 4.3 also provides optimizations for some newer CPU families (Intel Core2, AMD Barcelona, and others), so we’ve made those flavors available with this release.
Also a test tool has been released to cut the guess work as to what will be the best version to run,

"In the past, we’ve offered different CPU flavors of the module to hopefully provide the best encoding/decoding performance, but it was up to the user to install and test each flavor to determine which one provided the best performance. This process is difficult and time consuming, and did not always provide reliable results. To help with this situation, we’ve now released a tool called ‘benchg729′, which can be run on the target system and will execute encoding speed tests (using a real audio sample) for each CPU flavor that we offer for that platform, and then report the results and suggest the best performing module flavor for that system. Note that the use of this tool requires that the system have at least one valid channel license for the Digium G.729 codec installed; it will not run without a license."

VoipUser.org, the largest open-source VoIP network,
has announced the interconnection of British Telecom 0870 range
numbers to the VoIP peering iNUM network.
"VoIP remains restricted by the lack of interconnection between
networks," said Dean Elwood, founder of VoIP User. "By interconnecting
to the BT 0870 range, we have enabled cross-network calling for 14
million users which is free of charge at off-peak times. What we have
achieved today is the extension of our service into a new network of
over a million VoIP users".
British Telecom Plc, the UK's largest telecom provider, announced
that from 16th January 2009 it will make 0870 numbers free to call to
subscribers on their Anytime call plan.
John Peter, managing Director of BT's Consumer Business, said in a
Press Release on Thursday "All of our 14 million Anytime customers have
free calls included in their package and now all 14 million have free
calls to 0870 at times that fit with their calling plan, which is
something not offered by any of our competitors."
Ian Plain, of technical consultancy cyber-cottage.co.uk, who
architected the system for VoIP User, said "we created a mapping
service for the 0870 iNUM interconnect. The system is accessed by users
dialling 08700 68 58 48 from a BT landline and entering an iNUM number
to contact. Details can also be stored meaning that the caller only
ever has to enter the iNUM number to contact once." |
