We have a sonicwall firewall that is in place in our network. We just had a new phone system put in that will allow vendor to get to it remotely and allow main office to transfer phone calls to branch offices by using VOIP. There are times where the VOIP feature does not work and the vendor states that the sonicwall is blocking VOIP traffic or packets to their phone system. We have opened up the ports they need and there are still issues. They have ran wire shark to show us that that something is blocking the traffic.
If I upload these files can someone read these and tell me what is blocking traffic? They have wire shark files between the sonicwall and phone system.
Can someone assist me by reading these and letting me know if it is the Sonicwall?
