Re: [Sip-implementors] dhcp lease renew on ring

Hi Josh, One last followup: I was curious to see exactly what happens when dhclient renews my IP address, so I captured it with wireshark and found that in the DHCP request, dhclient specifies the IP address it is requesting to be renewed (the same IP that was originally leased). The DHCP serv

Hi Josh, What leads you to believe renewing a DHCP lease will drop your call? Think about this: have you ever had an HTTP download break because your computer needed to renew it's DHCP lease? I've never experienced such a thing. I'm not an expert by any means with DHCP, but if your computer se

Hi Nitin, You can capture the RTP near the UAC and see whether the media is coming up to the UAC after 183. If media is coming to the UAC, there might be a setting in the UAC to enable playing RTP after receiving 183. I have seen such configurations in some of the end points Hope this helps BR,

Is this a trick question? A *client* never sends responses. The thing that sends (any) response is an server. I guess the question is whether there is any case where a UA can send a 482? Thanks, Paul On 3/30/2011 10:57 AM, Brett Tate wrote: >> Is there any scenario or use case
