With greater acceptance of IPPBXs in businesses, loggers also had to follow the change. This change is quite huge because instead of decoding digitized information on each individual extension, all extensions’ packetized information is now found on the network. A huge advantage is that logger wiring is now less cumbersome as only 1 network wire is required (just like digital trunk logger). However, in order to install your own VoIP logger, you now need to have knowledge on the network and switches as well.
IPPBXs comes in 2 type of protocols, H.323 and SIP and many codecs. There are some loggers that work only on SIP protocol so it is good for you to verify with the PBX vendor before making any logger purchase. Our Voip logger is a software only solution. This means it is more cost effective, but it also means that the number of channels recorded is dependent on the CPU processing power (host-based).
A hardware based Voip logger solution means that a single logger (with voip decoding card) will be able to record up to hundreds of IP Phones in use at the same time utilizing very little of the CPU resources. So your choice of software or hardware based voip logger will depend on the number of ip phones you intend to record now and 2 years down the road.
