333with skype
I've seen some things online that show you hi.
333Re:
What about these products? Are they not reffering to specific product to draw traffic?
http://asterjet.googlepages.com/voipinternational
http://www.indafon.com/signin
How do you imagine the right article not reffering to any producer?
333
The only reason for your posting is to draw traffic to the 2N website. The description is very generic and if one visits the actual page you're only referring to a scenario made possible by another vendor, Nokia. There is nothing newsworthy to that, as the SIP support has been there for some time and is fully documented on http://www.voip-info.org/wiki/index.php?page_id=3363.
333to spamblock
could you, please, be more specific then "that type of ´news´"? What is wrong with the news about SIP client in the mobile phone
and with manual how do that? At least, when you are so brave to erase someone´s links, be so brave and provide some information
about yourself and don´t choose "private" mode.
Thank you for your reaction or email info, so we can discuss each other´s opinion.
