[Serusers] Manipulate malformed contact header *before* REGISTER processing

by Kanakatti Mahesh Subramanya

Is there any way to manipulate a malformed contact header in a REGISTER packet *before* we run it through proxy_auth, etc.? I've got a couple of phones behind a Cisco router, which insists on lopping off part of my Contact header. Basically, my inbound REGISTER packets shows the contact header as Contact: <sip:foo.bar@192.168.1.1:5060;transport=udp;line=8hzddhav>;q= (note the trailing 'q=') What i'd like to do is append a "1.0" to the header, and *then* run it through the proxy_auth, etc., etc. If I do a subst(), it doesnt seem to help. Any ideas?

[Serusers] sems & nat

by Giovanni Balasso

hi {ser+sems}users, i've installed sems and ser with nathelper and rtpproxy all from cvs, ser and rtpproxy work fine, i can talk to people inside and outside nat, but I can hear sems ivr only if i call from inside the nat where ser+sems is runnig. Has anyone some experience with nat and sems? May I run ser+sems from inside a nat with port forwarding (as I am doing now) or will this preclude sems from working in any case? I thought I should have to pass thru rtpproxy, but I don't know how to deal with ser+sems fifos and rtpproxy. reading from the following debug line it seems that no address translation occurs in the communication between caller (192.168.1.111) and sems (192.168.1.125, the two private IPs belonging to different networks) (997) DEBUG: run (AmIcmpWatcher.cpp:133): ICMP from 192.168.1.125: type='Destination Unreachable' src=192.168.1.125:36032 dst=192.168.1.111:8000 Thanks -- Giovanni Balasso giaso(a)yahoo.it

[Serusers] Bug with allow_trusted ?

by Francesco Bottà

Hi all, maybe it's a bug in module permissions. I'm trying to use the allow_trusted function to trust my SIP/DSS-1 gateways.

[Serusers] MediaProxy Not Showing The Traffic

by Doug Eubanks

I am making good progress, however I always seem to have NAT issues with nathelper, so I am trying to use MediaProxy. I have it installed, and the calls are showing up on the Media Sessions page, but they always show as "Status: inactive" and never show any actual traffic. Also, the client that is behind NAT (or not) can not pass any voice traffic in or out. If I run the rtpgenerator.py it shows the test rtp with traffic flowing. Any ideas? Thanks, Doug

[Serusers] SER-0.9.0 Multiple-domain

by Helge Waastad

Hi, I've got a question which may or may not have been answered earlier. I'm running ser-0.9.0 with two domains, <domain-a> and <domain-b>. (serctl domain add <domain-a>/<domain-b>) I've added <user-a>@<domain-a> with password <password-a> (serctl add <user-a>@<domain-a> <password-a> <email> Both modules registrar and userloc has use_domain=1 Default SIP_DOMAIN="<domain-a>" Registration with <user-a>@<domain-a> and password <password-a> works, as usual, fine. If I modify my user to register as: <user-a>@<domain-b> and password <password-a> and it still is registers OK! Is this how it should work? I would expect that the client should not be able to register using another realm... Best regards, Helge Waastad

[Serusers] avpops module

by Richard

Hi Elena, I have a few questions in regards to avpops. Hope that you can help. 1. When avp_pushto() is used, the ruri is only used when t_relay is called. However the uri match can't match the regular expression correctly. For example, I have this, avp_write("sip:nobody@test.com", "s:default"); avp_pushto("$ruri", "s:default"); if (uri =~ "^sip:nobody@") { xlog("L_INFO", "got nobody\n"); } else { xlog("L_INFO", "didn't get nobody\n") } It would say "didn't get nobody\n". If I run t_relay, then it is sent to sip:nobody@test.com. 2. Is it possible to have a function to copy an avp to another avp? The application is this, tm module uses one avp to define the invite timer. If there are multiple timer values defined for different scenarios, we need to copy the value into the one used in tm module. For example, s:pstn_invite=100, s:sip_invite=20, If (the call is to pstn) { avp_copy("s:pstn_invite", "s:callee_fr_inv_timer"); } else { avp_copy("s:sip_invite", "s:callee_fr_inv_timer"); } 3. For performance reasons, we'd like to group all user preference in one domain in one mysql table. Is it possible to specify the table name with an avp? Regards, Richard
