The problem arises because VoIP uses dynamic UDP ports per call. This causes problems when traversing a NAT device for two reasons; the NAT device changes supply port of outbound packets as part of the NAT process. The second is because UDP because of its demands is for one way traffic (broadcasts, video stream etc). Where TCP users are bi-directional throughout the one connection UDP get 1 connection for inbound and another for outbound meaning they have found that use different ports. If the inbound connection uses different ports as your outbound connection the inbound traffic is dropped because the NAT device does dont you have a mapping for it in its NAT platform. If you are confused document I suggest you inform yourself on NAT first.

In most SIP environments there become several VoIP calls being concurrently. Almost all these calls end up being managed through the VoIP switch, each one requiring an voice tube. Each channel (or phone call to analyze it another way) must use a genuine port. If there are 100 concurrent VoIP calls in use there must be 100 ports available for your VoIP alteration to allocate to every call. This is when SIP is offered in. It basically controls everything that's needed in establishing the consider. For each call SIP will find a spare port, allocate it, send this data to all parties, set the call up and ring the cellular phones. Once the call has finished SIP terminates the session and informs cell phone switch this particular port can be reassigned to another call.
