Hi everybody,<br><br>One of my customers wants to buy IP Phones and Asterisk solution, but his requirement is if he'll not be happy with Asterisk, his phones should be able to work with other IP PBX systems as well, so that he doesn't have to buy new phones again. After all IP Phones is the main investment. He'll most probably go with Nortel IP PBX system if he'll be not satisfied with an asterisk system.
<br><br>Experienced folks among you, please advise which phones to offer him, Aastra, Polycom, Snom, or some other.<br clear="all"><br>Thanks<br>-- <br>Zeeshan A Zakaria
