Ignatios Souvatzis: > would you (or somebody else) please expand "DoV" for me? Data over Voice. For reasons of telco stupidity it is common in various countries (namely in Australia) that telcos sell 64 kbps channels that are used for voice services cheaper than 64 kbps channels that are used for data services. Hence DoV is a workaround which pretends voice bearer services but transmits data. Basically DoV is transmitting blue bits where only red bits are allowed. Which immediately brings us to the next question: What is the common color of a bit? :-) Seriously: A pitfall might be that voice could possibly be compressed on the long distance, in which case transmitting data of course won't work. On the other hand DoV is often used to connect to the local ISP, however compressing voice on the local loop is a rather pointless exercise.
