Dear All,

I would like to ask if the call from Lync 2013 mobile users (out side my network) to land line through the edge will required a specific ports, call will be like the following:

User in Home >> connect to Lync 2013 client (laptop or smartphone) >> Dial enterprise voice number "+180012355522" >> the call will route from Edge to Mediation server to voice gateway to PSTN lines

I know the following ports required for the clients to connect from outside, is there anything else:

53 TCP/UDP DNS (from Edge to Internet)
80, 8080 TCP HTTP Out (from Edge to Internet)
443 TCP (Bidirectional)
5061 TCP/UDP (Bidirectional)
3478 TCP/UDP (Bidirectional)


Thanks

The required ports for Lync Edge are as following
sip.domain.com ports (443 and 5061 tcp only)
av.domain.com ports (443, 3478 tcp/udp, 50000-59999 tcp/udp)
webconf port (443 tcp)

Meet.domain.com, dialin.domain.com, lyncdiscover.domain.com (mobility autodisocover), webservice.domain.com should all be configured on the same public IP on port 443 as they only connect using HTTPS when configured on Any reverse proxy like ARR for instance.

You do not need to do any other configuration.
