Incoming Call Issue with Belgacom BBOX
Posted by: Jenny in VoIP, VoiP Equipments, internet phone on June 3rd, 2010
Using VoIP for your calls is the “in thing” today. This is the best “TREND” I like since it promotes SAVINGS and HUGE HUGE SAVINGS! It feels good also to know that I am becoming to know more about gadgets and technology now after I used VOIP for my phone calls.
VoIP is making calls using internet access instead of regular telephone wirings. You can use VoIP on your mobile too if your phone has wifi or 3G network. At home or in the office, you can connect your regular phone to any VoIP device so you can make and receive phone calls. Do not forget to connect your VoIP device to your internet router or modem. You can also use your internet router as your VoIP device already. The catalog box of your router will tell you if it’s SIP/VoIP capable, if it’s not there, then don’t bother. That means, you need to get VoIP device and have it connected to your internet router.
Calls are great that the person on the other line will not notice that you’re not using the regular line (landline or mobile). The only problem is when your internet port is blocking SIP/VoIP calls then that mean you cannot receive calls. This is encountered mostly by BELGACOM customers with their BBOX. To resolve the issue, I saw this great video sent on my email as one of my so-called VOIP alerts (I am VoIP fanatic now). This is about changing the port 5060 to 9999 so that you will be able to receive SIP calls.
Wireless VoIP Handset Market to Reach 47m Units in 2009 – Report
Posted by: nomado in internet phone on January 7th, 2009
A new report from Disruptive Analysis has found that by 2009, there will be a market for 46.8 million Wireless VoIP (VoWLAN) phones, of which 64% (29.8 million) will be “dual-mode” cellular/VoWLAN devices. These will be able to connect to both ordinary cellular networks, and WiFi access points. The rest will be “single-mode” VoWLAN handsets, similar to today’s home or office cordless phones, but potentially with much greater functionality.
Many observers and industry participants had expected a significant role for “UMA” (Unlicenced Mobile Access) technology among dual-mode phones and new operator business models. UMA enables GSM-based cellular carriers to extend their services, via broadband and WiFi (or Bluetooth), into users’ homes, improving coverage and offering low-cost in-home telephony. The intention is for “seamless roaming” between cellular and WiFi domains. UMA’s advocates hope to continue the trend of substituting mobile calls for traditional residential fixed-line phone services.
But the study finds that just 5.5m households worldwide will use WLAN-based UMA services by the end of 2009, with 6.7 million UMA VoWLAN phones being sold during that year. Although UMA-based services are first-to-market in the FMC arena, limitations to the business model will stall roll-out and uptake, letting competing approaches, based on standards like SIP (Session Initiation Protocol), catch up. Simpler, “unconverged” VoWLAN services are likely to take the lead, ignoring the complexities of roaming in the short term.
UMA does not currently support 3G services, nor integrate with corporate telephony systems. Given that carriers are looking to upgrade their best customers to 3G services, providing them with new and expensive 2.5G/WLAN phones seems a retrograde step. Although Bluetooth-based UMA handsets will be inexpensive, WLAN-equipped ones are likely to be much more costly.
Other factors will also diminish the attraction of the UMA proposition.
Dean Bubley, author of the report and founder of Disruptive Analysis, explains “UMA generally ignores the existence of the user’s PC. But if a customer has a multimedia-capable, WiFi-connected device, using their paid-for broadband connection, he or she will probably want to link the two. For voice calls and basic coverage improvement, this isn’t a major issue. But if the phone is also an MP3 player and a multi-megapixel cameraphone, customers will be annoyed if it cannot access the PC’s hard disk – or benefit from the PC’s connection to the real Internet, to access email, music, VoIP or other services. There may also be complex security and customer support issues, connecting a UMA-phone via a customer’s existing WiFi access point, that mobile operators will struggle to deal with.”
