long distance voucher, duration? sip setting

[pshpang]

- any expiration or duration for each voucher?
- would the existing sip setting need to change per voucher? or account would get automatically update once voucher has been purchased?

No expiration or time limit on the vouchers!

No change needs to be done to the SIP settings when vouchers are purchased. Our server automatically knows that phone number xxxxxxxxxx has a balance of $xx for calling non-free areas.
