One x Mobile SIP IOS

[morenot]

Hi:

Somebody with Iphone working outside LAN..

I have Lab with MES 6.3, without SBC...
Inside LAN the Iphone works ok
Outside LAN, Iphone registered on SM, It can make calls, only signalization, but when the phone called answer, the Iphone is disconnected..
calls from phone to Iphone no work..

Maybe Ports problem..
Wath would be the port to be opened and where routed..

Thanks in advance

I think its a question more of mapping dynamic RTP ports that get used semi-randomly. That, and even then, the SM messages to the softphone would in its SDP say something like "send your media to this internal 172.16.x.x IP of the G450 gateway on port 20XX.

That's basically what SBCs are for
