We have recently moved to Mikrotik for our routers. We have many VoIP clients. On sites where we deploy Mikrotik routers we have discovered NAT issues for sip clients registering to freepbx hosted servers in remote data centres. It seems Mikrotik Nat is broken for sip. With routeros "sip helper" enabled or disabled, we have the problem of sip end points periodically showing "Un-Registered" If we replace Mikrotik with any other router like a snapgear or cheap dlink the problems go away. Here is a link to a person with a similar problem: http://forum.mikrotik.com/viewtopic.php?t=79039 We would like to consult with you if you think you could help us solve this issue as we would like to use Mikrotik routers because they are well priced and full of very helpful features.
