Hi David, We saw this during interop, but calls placed fine. However when we went to production, calls wouldn't go through. Turns out if your on e164+ they want the callerid to be +1XXXXXXXXXX and if you are on their national dialplan, they want it as XXXXXXXXXX instead.This is for rpid or p-asserted. This was for their SIP 2WAY service, our outbound only isn't up in production yet. Regards, Jared Geiger On Fri, Jun 25, 2010 at 10:07 AM, David Hiers <hiersd at gmail.com> wrote:

Hi, Do you peer with verizon?

Do you get peppered with their custom "Warning: 399" headers inside their 200 responses? If so, have you ever gotten a decent explanation of these headers?

Thanks,

David _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops
