A month or so back, a few members of Direct Brands‘ IT group presented to the Central PA VMUG (VMware User Group). The talk was focused on VMware’s View product and one item of special interest to me was how they got their SIP client software (soft phone) for Windows XP working on VMware View virtual machines.

Apparently, getting SIP softphone client software to work on a VM is not supported out of the box and some hacking of the registry is required to make the software functional.

Sarah Miller at Direct Brands was kind enough to provide me with a copy of the presentation and the registry hacks they used to get Nortel’s i2050 and Avaya’s IP Agent Release 6 working on their VMs. I have not tested this configuration myself, but Sarah reports that they have quite a few remote users with this setup working successfully. I believe that Direct Brands is using USB headsets with the VMware View Client in this scenario.

Thank you for the tip, Sarah!
