We have configured everything it seems correctly because we can receive and make calls to Intelepeer (sip provider). Now the problem comes when we setup call forwarding to an outside number in Lync. The call initiates but there isn't any rtp traffic flowing, and we don't get audio either way. Does anyone have any idea what is going on? Any advice?Anonymoushttps://www.blogger.com/profile/09296054471750034140noreply@blogger.comtag:blogger.com,1999:blog-4688688680584167129.post-57535853494604977122013-04-16T09:42:31.658-07:002013-04-16T09:42:31.658-07:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/09296054471750034140noreply@blogger.comtag:blogger.com,1999:blog-4688688680584167129.post-30949238548087650882013-03-19T10:09:26.554-07:002013-03-19T10:09:26.554-07:00Matt,

I've followed the suggestions in your bl...Matt,<br />I've followed the suggestions in your blog. After two days of testing with Intelepeer, and escalating the issue with Sonicwall, it appears that I will have to find a new SIP provider (or firewall, which won't happen.) <br />Sonicwall claims:<br />The NAT policies and access rules are configured properly. The NAT'ing happens in the network layer but on the application where the SIP lies the server is sending the request out (to Intelepeer) using its private ip address rather than the public ip. So please make sure that the server is doing the transformation for SIP.<br /><br />Just wanted to make sure others don't waste a lot of needless time if they are planning on using Sonicwall with Intelepeer, unless I am missing something...but I have no higher up to go with either vendor.Anonymoushttps://www.blogger.com/profile/03550862976388534430noreply@blogger.comtag:blogger.com,1999:blog-4688688680584167129.post-32557224757032345652013-02-21T17:07:00.075-08:002013-02-21T17:07:00.075-08:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/03550862976388534430noreply@blogger.comtag:blogger.com,1999:blog-4688688680584167129.post-42391056415824605452013-02-13T10:32:29.100-08:002013-02-13T10:32:29.100-08:00Matt - Two quick questions - is the scenario above...Matt - Two quick questions - is the scenario above for a Lync Server inside the firewall with Lync clients connecting from outside or is this for Lync clients inside the firewall connecting to a Lync server outside, like with an Office 365 scenario?<br /><br />Also - you mention Lync Media Ports and and have a LYNC-SIP-TRUNK-GRP service group defined.
