Hi Barry,

as you use quite an old devel version, first try to update with latest cvs version and let me know if the problem is still present.

Yes, have been trying but it appears the sourceforge CVS is out at the moment. Actually I have found that this issue only exists with SIPPS softphone. XTen, SJphone and other IP phones are all fine. Unfortunately, we are just about to roll out with SIPPS...oops!

Hi,

Using openser 1.1.0-dev8 as a registrar/proxy in from of Asterisk. Recently I have been getting errors from Asterisk due to corrupted From: headers, which appear to be caused by uac_replace. Here is a section of the debug log:

As you can see, the auto restore_from of the uri is putting garbled characters in there. This has only recently started in the past week. I have made no changes to openser in a month. The only thing I did was upgrade Asterisk to 1.2.5

Anyone any ideas?

yes, there is a partial outage on anonymous CVS - but you may try using the cvs snapshots from the openser web page.

OK, I'll give that a go.

Actually I have found that this issue only exists with SIPPS softphone. XTen, SJphone and other IP phones are all fine.

can you check on network level if the mirrored Route param sent by SIPPS is the same with the one placed by openser in the RR header?

How would I go about this?

Thanks.

Hi Barry,

indeed, there is a problem with this Nero SIPPS IP Phone - even if it receives vsf=AAAAAAAAAAAfGgQRSQADBEkACyVdABUuaW1hZ2luZS5pZQ-- it sends vsf=aaaaaaaaaaafggqrsqadbekacyvdabuuaw1hz2luzs5pzq--

so, it is case insensitive. The parameter is B64 encoding, so it is case sensitive.

The RFC says that the a SIP UA must mirror unchanged all RR parameters disregarding if it understands them or not. ,

Thanks very much Bogdan. At least now I know where to go for a fix!

Regards,
