[SIPForum-discussion] 180 Ringing not generated

[Kumar, Satish]

Hi Vidya,
You can check whether RTP packets are received from remote end to local end point thru sniffer. This may confirm the problem is at local end point or remote end point. If RTP packets are seen on the sniffer, your local end point is not handling them properly.

Hi Vidhya,

Ideally Ring should be generated from the last end ( Final Destination ) or the actual called party. You can not do much trouble shooting at your end , you could only show this to your next hop if that is also belongs to your company then to next hop to that.

One possible reason might be that called party is not generating 180 or its getting lost in network ( which wont happen every time ) or your server is not processing 180 ( For this you need to capture the packets coming in from next hop)

But if they are not sending then you can not do much trouble shooting.

Hope this helps

Cheers

Hello everyone,

I am just a beginner in SIP. I am sending a INVITE from one of the endpoints, but the other endpoint doesnt send 180 Ringing back. wat could be the possible reason for failure.
