Thank you for your replies.<br><br>@Olivier<br><br>Yes. The telco here (in Mumbai, India) charges more for p2p. See their tariff <a href="http://mtnlmumbai.in/telecomservices/isdntariff.html#bratariff">http://mtnlmumbai.in/telecomservices/isdntariff.html#bratariff</a><br>
It is mentioned in "Charges for point to point connectivity : ISDN BRA Lines" that extra charges would be applied for p2p. They have not mentioned any charges for p2mp so I'm assuming this is what I will be getting p2mp by default.<br>
<br>We plan to do speech recognition of the collected data, therefore would not prefer data passed over simulated channel. <br><br>@<span class="gI"><span class="ik"></span><span class="gD" style="color: rgb(91, 16, 148);">Tzafrir</span></span><br>
Yes p2mp might complicate the thing. It seems I have to explicitly ask them for P2P while applying. I mean that if I do not explicitly ask them for p2p, will <br>my card work (for whichever default connection they provide for ISDN handset) ?<br>
