Hi,

The problem seems to be related with the sendto() system call for RTPpackets.

It's in oRTP/src/rtpsession.c in function rtp_send().

sendto() returns an error. Invalid argument does not tell us whichargument was wrong:

socket, ipv6 address, data , data size ?

If you are a developer you should be able to find out the reason of theInvalid argument based on the suggestions I made above.Unfortunately I have no ipv6 network availlable for me to try toreproduce the problem.If you can provide me a ssh access on a public machine connected to anipv6 network, I can try to investigate the problem.

Hi,

I am trying to test linphone IPv6 clients with the IPv6 partysip server and 
have had some problems... hopefully someone can give me some suggestions as to 
how to fix things:

I have used linphone-0.12.1 (tar.gz file) to test v6 client - to v6 client and 
also v6 client - partysip v6 server - v6 client but encountered errors in both 
tests.  Error is at the end of email  (registration with the server was 
successful)

I also tried v6 client through a NAT-PT device to a v4 server then tried making 
a call to the PSTN... again registration was successful but another 
'oRTP-WARNING' was encountered.  The error from this is also at the end of the 
email.

Using v4 client - v4 client and v4 client - v4 server - v4client/PSTN works 
perfectly, no problems.

I had also tried linphone-0.12.1pre5.  This worked v6 client to v6 client but 
didn't work when trying to connect to a v6 server because the IPv6 addresses 
were shortened in the 'via, call-id and contact fields'  e.g.  
2001:618:f:501::%2 instead of the full 128 bit address.  (sorry I'm not able to 
include the exact output)  Any idea why the IPv6 addresses were shortened? Any 
solution to this?  The addresses were input correctly in the 'parameters' 
window.

Any suggestions as to why linphone-0.12.1 did not work for IPv6?  Have other 
people attempted similar tests and had similar problems?

Any help and suggestions you can give me would be appreciated.  If more info. 
is required please let me know.

Thanks
Fraser
