Re: [Linphone-developers] Can I get remote actual IP address, not one from SIP packet.

[Praveen Kumar]

I'm not exactly sure about how it can be done in Linphone Android as I've worked on the Linux based Linphone. 

But what I know on the basis of Linux based Linphone implementation is that Linphone uses "belle-sip" library to parse the SIP message. As I can see in the belle-sip library code they use "fix_incoming_via()" function in "belle-sip/src/channel.c", this function checks the remote host address & port in VIA header & compares them with the source IP address & source port of the received SIP packet. In case, they don't match the function overwrites & replaces the host, port values in VIA header with the actual remote source IP & remote source port of the received packet.

So, in essence, I think you can use the values present in the SIP Via header (as they're fixed in case of any discripency at the lower level itself).

Hello Praveen,

Any suggestion how we can achieve this? Do I have to make changes in C source or it would be possible to get in JAVA layer in linphone?

Hi Aniruddh,

The source IP address you shall read & use from actual UDP packet rather than from SIP packet for your case.

Hello,

I want to get actual remote address in my linphone Android application. All what I was able to find is address sent in SIP packet which can be sent by anytool. Thus, is there any way in linphone-android, using which I can get actual address from where SIP packet is coming ?
