[Users] Problems with Mediaproxy. Bad Port.
by Ricardo Martinez 27 Oct '06

27 Oct '06

Hello list. I'm having a problem with my mediaproxy box. I have a NAT'd client (a softphone) calling to a SIP-H323 conversor through my OpenSER-Mediaproxy box and then to a Cisco Call Manager (it's a very weird configuration). Anyway, the problem presents when the 200 - OK message arrives from my conversor, the SDP part indicate the media address (10.10.148.230) and port (16952) where the remote endpoint will listen RTP, despite of this the mediaproxy open a session for the port 17360. The escenario is something like this. 100.100.148.248 ------- 100.100.148.246 ----- 100.100.154.36 ------ 100.100.154.119 ---- 100.100.148.230 Softphone OpenSer/Mediaproxy Proxy Sip siph323 conversor Call Manager.H323 Please check the log from the mediaproxy and the execution of the "sessions.py" utility, plus the OK message.

Why mediaproxy assumes the 17360 port is for listening too and ommit the SDP 16952 port ? Is this maybe an asymmetric regarding the RTP media?. If so, i added this line into the rtp-asymmetric-clients file: # # Lines starting with a '#' character or empty lines are ignored. # Put a User-Agent name or regular expression per line. # Check is case insensitive. # # This file should only list SIP clients that are asymmetric regarding # the RTP media streams. For clients that are asymmetric regarding the SIP # signaling, use the equivalent SIP version of this file. # Clients that are asymmetric for both SIP signaling as well as RTP media # streams should go in both files. # siph323 But not solve the problem. Can someone help me here? Thanks in advance Regards Ricardo Martinez.- RedVoiss.

[Serusers] variables in log messages
by Mark Price 26 Oct '06

26 Oct '06

Is there a method to print variables into log messages? For example, something like this: instead of saying: if(method=="SUBSCRIBE") { log(1,"SUBSCRIBE\n"); } do this log(1,method) which obviously doesn't work. It would be very helpful to be able to print out things like headers. Perhaps the select or more likely AVP functions will work in 0.10? Is there anything available now? Mark

[Users] Replication ACK problem
by Dioris Moreno 26 Oct '06

26 Oct '06

Hi everybody I have a working installation of OpenSER (Proxy A). In this installation, the ACK messages are delivery without any problem through loose_route() and t_relay(). Then, I installed a second OpenSER proxy (Proxy B) and configure both servers to replicate REGISTER messages with t_replicate(), and it works fine. I made a lot of captures to check the replication process was working fine and also to check the NAT pings; each proxy takes care of the NATed clients it receives sending OPTIONS message periodically. I'm using mediaproxy to support NATed clients; to avoid each proxy starting a media session when it find a NATed client I used the following rule: a proxy receiving messages from another proxy never starts a media session, the proxy that sends the message takes care of that. Having two registered clients (Client A in Proxy A and Client B in Proxy B), I start making calls from Client A to Client B, but I found something in the captures. All the messages flow correctly, except the final ACK message sent by Client A to Client B. Proxy A receives this message and pass it to Proxy B, but Proxy B never deliver it to Client B. Of course, the media session never starts. I was searching info about this situation and I found an email respond from Bogdan about using t_newtran() to process ACK messages, I tried, but it didn't work. Has anybody ever had the same problem? Is there a special way to deal with ACK messages when we're working with replicated proxies? I'll appreciate any help.

[Users] Changing call ID?
by Olle E Johansson 26 Oct '06

26 Oct '06

I got a bug report in our bug report tracker for Asterisk that claims that SER changes the call ID by adding a :port after the IP address. From reading the RFC, I don't think it's a valid change. For me, it's a new call ID. Questions: - Is changing a Call ID permitted within a dialog? - Does SER/OpenSER actually do this? http://bugs.digium.com/view.php?id=8220 See you at the Summit in Berlin! regards, /Olle
