Peter, Thanks for that. It's great info. Unfortunately, I cannot reach the customer's end-point using that approach. I must infer that, in this case at least, they are not on the Broadsoft platform. Or it is in some way defeated.

And VB is on BSFT. Vonage consumer: When I was a vonage user people could dial me by calling: sip:{Vonage_Phone Number 10 digits}@sip.vonage.net. This is a SIP URI but it would be much more clean if they had created SRV records for vonage.com.
