Perhaps you should contact there tec support and explain what happened and that you want that account deleted. It would seem to me that it would be deleted automatically after a while. I'm sure they are not monsters, lol
Are you able to login to a blocked account?
For outgoing calls simply use your phones browser or the free googlevoice call back app available in the android market. This is not the official googlevoice app. Or log in to your google voice account via your web browser enter the number you want to call and you will be called back via sipdroid and your call will then complete. Make sure in google voice settings that you tell it to all you back.
The callback app is the easiest way to go as far as dialing out. All that happens is you get called back on sipdroid. If you feel that pbxes is somehow holding onto your google chat credentials it wont matter because you simply uncheck it as a forwarding option in google voice and use the ipkall number. This is a pure VOIP solution and works well if pbxes is having problems or whatever.
alternatives to ipkall are sipgate and ipcomms.
here are all the links.
