If it helps, the first branch and the comma separated list of all branches can be written in an AVP using the pseudo-variables $br and $bR with avp_printf() - http://www.voice-system.ro/docs/avpops/ar01s06.html#avp_printf .

Hi Richard,

only the RURI will be written into AVP - the branches will be ignored. Do you see a case for this? because it can be implemented quite easy.....

Hi,

If there are multiple branches, will avp_write("$ruri/username","i:123") generate multiple avps with each for one branch? Or it only grabs the first one?

Thanks, Richard

Hi Richard,

for NAT traversal, will be more logic to have the media going directly only if *all* branches have same IP with the src IP - you do not know which branch will succeed and you can enable/disable RTP relay for all or for none.

avp_printf() is able to print all branch URIs in a single AVP, but not sure if this will help you.

The application of this is for checking if any of the branches ip address same as the source ip,

If all of them are the same as src_ip, I can have the media going directly between UAs.

Bogdan, is avp_print capable of implementing this?

Thanks, Richard

That's right. If all addresses are in a list of avps, i can use avp_check to check 'ne' to verify.

one more thing - you should check dst_uri and not RURI - RURI may be the private addr when the dst_uri is the public IP.

Not really. If it is not too hard to extend avp_write(), can you please add it?

It's doable, but I cannot make any time promises since I already have a quite long list with pending stuff to do - but with first occasion, I will go for it....

I have better understanding of dst_uri and ruri learned from another email thread. So for natted UA, dst_uri and ruri are in pairs. Would it be useful to save and load both in functions avp_write and avp_pushto? That's the problem I ran into at http://mail.iptel.org/pipermail/serdev/2005-August/005339.html. I tried to send a call to two users by loading both their locations. I first change ruri to user 1, lookup, avp_write to save it. Then I change ruri to user 2, lookup, avp_write to the same avp. At this time, the avp has both users' location. But when I avp_pushto the avp, it only load the ruri, not dst_uri. So the natted UA can't receive the call. This problem can be solved if avp_write and avp_pushto save/load both dst_uri and ruri.

you can backup the dst_uri (via avp_printf() ) but you cannot restore it at this moment. avp_pushto() has to be extended to support it. I am going to add a few new pseudo-variables in a few days (as discussed on the mailing list) and try to update avp_pushto() as well.
