First Release, no bugs.
Feature and Function Added
  1. Added the field —Route in Re-Invite packets for Call Hold
  2. Increased the allowable range of the sequence number field in packets. If the differences of the sequence numbers are overly large between packets, the device will reset the sequence number value within an allowable range in order to avoid problems that it may cause.
  3. New formula for SIP Expire Time. If SIP Expire Time > 120, then the calculation will be SIP Expire Time minus [(expire time/30)*6], if the SIP Expire Time < 120 then the calculation will be SIP Expire Time minus 5. If the SIP Expire Time = 120, then the formula is SIP Expire Time minus 5. The unit is in second.
