My Computer is connected in the Lan of the company and my E2500 is connected in this Lan too. My Server SipXecs and my hardphone are on the E2500.
So there is an other router between my computer and the router that have my Server connected on it. For the Wireshark part when I answer the phonecall I do from the softphone to my hardĥone those request are coming in until i close the call. 109 19.596310 192.168.175.22 192.168.175.136 SIP/SDP 1466 Status: 200 OK, with session description Status-Code: 200 [resent packet : True] [Suspected resend of frame:104] [Request Frame : 57] [Response Time (ms): 10950] followed by this one: 110 19.598495 192.168.175.136 192.168.0.1 SIP 714 Request: ACK sip:[email protected]:5060;transport=tcp Request-Line: ACK sip:[email protected]:5060;transport=tcp SIP/2.0 Method: ACK Request-URI: sip:[email protected]:5060;transport=tcp [Resent Packet: False] [Request Frame: 105] [Response Time (ms): 512] All those test have been done on Wireshark on the Computer with the Softphone on it. And the 192.168.0.253 that you see is the hardphone IP adresse. 2012/4/19 Gerald Drouillard <[email protected]> > On 4/19/2012 3:25 PM, Simon Brûlé wrote: > > How can I do a capture with wireshark on the SipXecs server? > > If you google a little you will find it. > > > About the ALG you think that the other Router that give the DHCP to my > Laptop and the Wan adresse of my router would have the Sip ALG activate? > > That would be the only thing inbetween your softphone and the sipx > server... right? > http://screenshots.portforward.com/Cisco/Linksys_E2500/Management.htm > > > > 2012/4/19 Gerald Drouillard <[email protected]> > >> On 4/19/2012 2:58 PM, Simon Brûlé wrote: >> >> I added 192.168.175.0/24 to the intranet subnet and I still have the >> same problem. >> >> 2012/4/19 Gerald Drouillard <[email protected]> >> >>> On 4/19/2012 2:37 PM, Simon Brûlé wrote: >>> >>> Hi, I know I already posted something very similiar to this problem but >>> I haven't found a solution to it so here i am reposting my problem but with >>> more precision this time. >>> >>> I have a softphone (Jitis) on a Ubuntu 11.10 installation connected to >>> the network of the company. >>> >>> I have a router Linksys E2500 connected to the same network.
