We are working with a local telecoms company that have asked us to quote for a firewall for one of their clients to handle VOIP traffic only.
We are used to working with Sonicwalls but not specifically for VOIP or SIP trunks and our knowledge of these areas is limited.
The connection is on a 100mb leased line and will handling 2 - 3 SP trunks.
After some reading I got a little concerned that Sonicwalls might be a nightmare when it comes to using them with SIP and VOIP, is this the case?
Also whats the best way to decide on what type of Sonicwall device would be best for the job? IE do I need to know how many calls will be made etc?
