[Users] Use STUN always - is there any downside?

[Barry Flanagan]

Hi,

We are using SIPPS as the softphone for our ISP customers, all of whom
are on DSL and behind some sort of NAT'ed firewall.

SIPPS does not always pick up the need for STUN when it checks the
network, and then the user has problems until STUN is enabled.

My question is - would there be any downside in us just hard coding the
client to use STUN, given that the end user is a home user on DSL?

Thanks.
