My Thoughts - Technology
Hi Folks, today morning I was dreaming that why cant we have a device like the one as below,
A device which can have a option to insert sim card but it supports only data, not voice from telco service providers (Airtel, Vodafone, etc..)
Normally, if you take any mobile device it will support both voice and data (GPRS) nowdays 3G is coming into picture, if you take tablet and laptop it will support both wifi and wired network connection.
What I though is why cant a device support only data network from the GSM towers, so that a tablet can have a option to insert a SIM card which supports only data connection. This is because nowadays tablets are booming up, and it is easier to carry better then laptop, even in laptop also we can introduce this kind of option. If we roam outside we dont need to find out any wifi hotspots or any wifi access point, simply we can use as a mobile device only for data connection not for voice calls.
Feedbacks would be much appreciated....

Why is Asterisk not a SIP Proxy?
Asterisk is *not* a SIP proxy. A SIP proxy handles call control on behalf of other user agents (UA) and usually does not maintain state during a call and therefore is never the endpoint of a call.
Asterisk, as a server, is a SIP registrar and location server and also acts as a useragent endpoint (softphone).
If it is 'controlling' or relaying a call from a SIP phone to another SIP phone, it simply acts as an endpoint UA to the originating call leg and then creates a new call to the receiving phone. Therefore, it stays "in the middle of the call," maintaining state and controlling, and optionally bridging, each remote endpoint. The audio channels (RTP) may go directly from phone to phone or may go through Asterisk's media bridge.
Asterisk can thus be described best as a "back-to-back user agent" (B2BUA), which is also consistent with the use of the term "PBX". Because of this architecture, fairly simple SIP functions, such as REFER (transfer) involve more aspects of the Asterisk core. On the other hand, the architecture provides additional power and flexibility, because each call leg can just as easily be replaced with a different technology channel (ZAP, H323, MGCP, etc) and, thus, Asterisk becomes a powerful media gateway.
