Hi, Thanks for your suggestion, I have tried it and I am able to do a Inbound call via Nexmo now. But still I am not able to make any outbound call from my application. I have checked the FreeSwitch log by siptrace enable and found that my call was terminated with a SIP message as " IP/2.0 407 Proxy Authentication Required". Please find the siptrace log for my call as an attachment. and let me know what changes or configuration I need to make for Proxy Authentication Header. Thanks, Regards, Manish Talwar ________________________________ From: freeswitch-users-bounces@lists.freeswitch.org <freeswitch-users-bounces@lists.freeswitch.org> on behalf of Aviv Shaham <aviv@sent.com> Sent: 06 November 2014 14:39 To: freeswitch-users@lists.freeswitch.org Subject: Re: [Freeswitch-users] SIP trunking with Nexmo Hi Manish, Nexmo expects your API KEY to be in the From header. To set the caller ID you will need to use "caller-id-name". Good timing btw, I just posted a reply to a similar question on Quora. Have a look: http://qr.ae/DEbk2 - also covers Plivo.
