Hello, I have Cisco 3640 with Voice and E1 card connected to Nortel PBX for call out from PBX to PSTN. I have problem when 1. user hang-up the phone and got dial tone from PBX 2. dial prefix 9 and telephone number (9,024455566) 3. user will got dial tone again from Cisco 4. If user dial telephone number again, it can go to PSTN. (024455566) User ------ > PBX ----- > Cisco 3640 ----- > SIP Server ----- > PSTN Have you ever found this case?

[Serusers] Mediaproxy on Multiprocessor System
by tcchan 18 Nov '05

18 Nov '05

Hi All, I run mediaproxy on a 2 CPUs machine (Fedora Code 3). When I stress the mediaproxy with rtpgenerator locally, i.e., just rtpgenerator.py --count=50, I noticed that the load is distributed evenly between the 2 CPUs. But when I stress remotely, using a seperate PC, i.e., rtpgenerator.py --ip=x.x.x.x --proxy=y.y.y.y --count=50, where x.x.x.x is rptgenerator's ip and y.y.y.y is mediaproxy's ip, I noticed that the load is mainly taken by CPU0. Can someone tell me what happenned? Has anyone encountered this? If it is python problem, then why it can distribute the load evenly when stream locally? Kernel Problem?? Code??? Thanks for any help available. Regards, TC Chan

[Serusers] UPDATE instead of re-INVITE and RTPProxy
by Ronald Voermans 18 Nov '05

18 Nov '05

Hello all, I have a problem with some user-agents (namely Grandstream and Cisco ATA 18X). My SIP provider provides a UPDATE instead of a re-INVITE, because the mentioned user-agents support the UPDATE method. However, SER/RTPProxy doesn't know how to handle this UPDATE request, and forwards the request to the user-agent. Result: one-way-voice. Does someone know how to solve this. I solved it for now by replacing the UPDATE in the request, so the SIP provider doesn't see that my user-agents supports the UPDATE method. Thanks in advance, Regards / Met vriendelijke groet, --------------------------------------------- R.L.L.M.

[Serusers] Need help: SER and MYSQL issue: PID file /var/run/ser.pid does not exist
by Dhiman D Chowdhury 18 Nov '05

18 Nov '05

Hi all, I need help to fix the following issue which only occurs when I am loading mysql.so. The problem is that serctl will fail to start SER and sometimes if SER start with service SER command. SER process is not found. I have observed that for all those issues, the cause is as system log as follows: Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: Maxfwd module- initializing Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: new_connection(): Client does not support authentication protocol requested by server; consider upgrading MySQL client Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: db_init(): Could not create a connection Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: ERROR: uridb_db_ver: unable to open database connection Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: ERROR: uri_db:mod_init(): Error while querying table version Nov 17 20:26:12 voice /usr/local/sbin/ser[2753]: init_mod(): Error while initializing module uri_db When those situation occur SER always unable to start, please see this message: Starting SER : PID file /var/run/ser.pid does not exist -- SER start failed I think it is to do with mysql connection. I will appreciate if someone, please help me how to fix this. I am sure a number of other people will be facing this issue as well. Please help !! Please Help! Thanks Dhiman

[Serusers] mediaproxy module: RTP packet mapping after reINVITE with new SDP
by Joel Rosenfield 18 Nov '05

18 Nov '05

As I am new to this list, please tell me if there is a more appropriate list to which I should post this question. Does the mediaproxy handle changes in the media description within the same call dialog? If not, are there plans to do so? Here is what I have done: I am using the SER mediaproxy module v1.4.2 and a co-located proxydispatcher and mediaproxy to accomplish NAT traversal between a 3PCC and an remote ATA. All basic call scenarios work fine. However, when the module receives a reINVITE to reconnect the ATA to a different party, the mediaserver fails to forward the RTP packets between the ATA and party described in the new SDP. I saw in the mediaproxy logs that RTP packets had been received from both sides, but the signIn method was being invoked as "called" for both parties. I explored the rtphandler.py and saw that the "catchall" clause at the end of RTPStream.handle_read was being invoked as you can see by the debug statement that I added to the code. It appears that this is invoked because both parties had already signed in based upon the previous media description, so none of the other mapping/forwarding clauses are invoked. It seems that there needs to be a mechanism to clear the mappings when the mediaproxy receives a "request" command for the same session (based upon the SIP Call-ID) but a new SDP. I got it work by adding code to the beginning of RTPSession.updateStreams() that clears the list "mediaStreams" and letting the rest of the code in that method recreate the mappings from scratch. See the attached file containing the code, a mediaproxy log before the change, and a log from after the change. Although this works, the solution is a bit incomplete since it can cause brief interruptions in the RTP stream when a reINVITE is received that does not include an SDP change, etc. Please let me know if there is something I am missing with respect to how I should using the mediaproxy.
