I recommend setting a flat fee that assumes they will forward it off network and bill that.
It's rare that companies discount anything SIP or on network unless they're a budget VoIP provider targeting a highly technical budget-oriented market. Even then some do and some don't.
We charge our direct TF customers 4.9 and assume it will go to an external destination. We don't offer any discount for on-network or SIP for that...only the resellers get that.
Kall8 would be the primary competition for toll-free and where the majority of our TF customers that port come from. They're 6.9 cents.
Our 4.9 has plenty of margin for external forwarding and people still see it as saving 2 cents and are happy.
The key with VoIP in general is to not worry about other VoIP providers and compete with the landline companies. 86% of our port-ins come from landline. Even though there may be some cheaper VoIP options out there, 99% of users don't use VoIP and are very happy to see the huge savings over landlines.
