Krish,
it’s all explained in this post, check out the past posts.
If you have more questions, read 3GPP about Tandem Free Operations.
Ivann,
Weird about the lost email. Nevermind, I’ll let you do your analysis. On my side, the voice quality samples do not show any difference at all, so I can’t really use them to advertise for TFO activation worldwide.. can I ? 🙂
If you need any alcatel GSM training in Russia, please let me know 🙂
Cheers,
