Random Ports Used Behind SBC

[TBWD]

Just installed new PI at a new office for a client, Installed 2 new Snow D785 Phones have been provisioned and are using the SBC, but are on random ports,
Any Ideas?

Already seen this on my install with SBC, it seems to me this is always like that

Thanks for the info, so this is normal?

Hi Christopher,

This is not necessarily something to worry about. You are seeing the SIP source port the phone listens to and registers from. It does not have to necessarily be 5060, so long as it connects to the SBC destination port 5060, it can come from wherever.
