Hi
I have some issues with SIP handsets, the NAT tracking is higher than the external SIP provider for hosted handsets - this causes issues sometimes where the port mapping has closed but the ITSP still has a binding to that port so timesout when it sends a phone call
I have experimented with extending the tracking timers on the Mikrotik but this isnt working how I want.
What I think will work is setting my 10 x handsets to static DHCP entries and then creating a static NAT binding for 5060 for each handset on outbound connections.
so example
Internal
handset 1 - 10.10.10.11:5060
handset 2 - 10.10.10.12:5060
handset 3 - 10.10.10.13:5060
external over public ip 77.66.55.22
internal / external port bidning
handset 1 - 5060 > 506011
handset 2 - 5060 > 506012
handset 3 - 5060 > 506013
any ideas how this will look like on Mikrotik config ?
Ive done quite a few inbound port maps but this is slightly different as its doing it in the opposite way
