[Serusers] FCP module getting ready for testing...

by jaime＠umtstrial.co.uk

Hello, The FCP module for SER seems to be approaching to a stable version (no guarranties, though). The module is in charge of 2 functions: - Translation of SIP messages from a private network to a public one (using NAT). - Open and close pinholes in a firewall to allow media sessions through. The module implements the FCP side that communicates with a deamon called fcpd that runs on the firewall itself (developed by iptel: http://www.iptel.org/fcp/). It seems to be reasonably stable now with cvs version of ser from 31/03/03. I'm looking for anyone interested in trying it and provide any feedback (bugs, new features or complains :)). Greetings, Jaime

No. What you need is standardized call transfer support in your phone. -Jiri

[Serusers] serweb and fifo

by Meghan Patricia Byrne

I've successfully installed serweb and am able to log in. However, once I do so, I get the following error: Warning: fopen(/tmp/ser_fifo) [function.fopen]: failed to create stream: Permission denied in /usr/local/apache/htdocs/serweb/functions.php on line 172 at the top of the screen, and the message "sorry -- cannot open fifo" in red letters on the webpage above the user's information. I'm wondering if ser or apache needs to be configured somewhere with the correct permissions or ownership to make this work. Thanks!

I'm not sure what exactly happens from your narration. The terminology is little a bit new to me -- forwarding means imho sending a 3xx reply to an INVITE and not BYE requests. A message dump would help me to understand. Anyway, I don't think that is an issue related to SER -- it is about end-device features. -Jiri

[Serusers] Regarding NOTIFY

by Geetha Shree

hi all, We wanted to know whether the SER server will just Proxy the Notify method or else it gives the 200OK response also. When we sent the Notify method, it just proxied to the contact ip address but did not send the 200OK response to us. Thanks Geetha

[Serusers] bug in last changes for "rport-received" tags

by Sergio Miguel Garcia

I have been testing the last changes about the "rport-received" tags, and I have found the next bug: when using UDP transport, if the IP address and port in the "Via" field differ from the IP address and port of the incoming packet, the "received" and "port" tags added to the Via of the response are correct, but the packet is sent back to the "received" IP address BUT to an incorrect port ( this should be the "rport" port ), that generates an ICMP "Destination unrecheable port". I have been capturing these packets and I think I have found exactly where is the problem. For example in the next sequence: 1)REQUEST PACKET: ( REGISTER for example ) Source: 192.168.1.2:1667 Destination: 192.168.1.3:5060 "Via: SIP/2.0/UDP 192.168.1.100:6969;rport" 2)RESPONSE PACKET: Source: 192.168.1.3:5060 Destination: 192.168.1.3:33542 <- HERE IS THE PROBLEM, this should be "rport" "Via: SIP/2.0/UDP 192.168.1.100:6969;rport=1667;received=192.168.1.2"<-but this is correct 3)ICMP PACKET: Source 192.168.1.2 Destination: 192.168.1.3 Type:3 "Destination unrecheable" Code:3 "Port unrecheable" I've been checking other pairs of ports sent and received like 1667-33542, 1507-58117, 1509-58629, 1511-59141 and the second is the network address order of the first ( 1667 = ntohs(33542) ) . I think that you forget to make a htons() of the port received in host format before sending the packet back to network. Please, let me know when this issue is solved in the CVS. Best regards and congratulations for your excellent work. Sergio.

[Serusers] workaround for bug in snom's RR-ing

by Jiri Kuthan

fyi (in response to a frequently asked question "how to get snom's buggy RR-ing working along with PRACK). I just tried to create a workaournd to the problem (which is PRACK does not put Routes learned in 183). It's as easy as mangling SIP messages not to advertise their support for "100rel": if (method=="INVITE" && search("User-Agent: snom")) { #replace("PRACK, ", ""); replace("100rel, ", ""); }; -jiri -- Jiri Kuthan http://iptel.org/~jiri/
