[Serusers] problem for Cisco 7912 ip phone behind pix firewall

by sekchye goh

Hi there! We have two cisco 7912 ip phone using SIP firmware behind Cisco PIX firewall. These two phone is configured to register to a SER proxy which is on the public Internet. These two Cisco 7912 ip phones are PATor NAPT to a single IP. The problem we have is when these two phones call each other, the two party cannot hear each other's voice. If we replace the PIX firewall with a Cisco router, there is no such problem. Does anyone encounter this problem before? I am clueless on how to resolve this problem. Any pointers will be much appreciated. Thank you very much! Best regards sekchye

[Serusers] ASCII SIP UA ? (like wget for SIP)

by JOHN J. BARTON

Hi. Is there a tool like wget for SIP? Seems like it could be useful at least for testing and admin scripts. I know that SER has fifo on server. Is there some trivial way to use it from a remote machine? Thanks, John.

[Serusers] Strange SER hanging problem

by Jason Ostrom

Hello all, I have not been able to get my SER to work properly on this SuSE Linux Pro 9.2 machine. SER appears to hang endlessly. The binary compiled from src just fine. I can't tell exactly where the problem is, can anyone lend help in deciphering where to find the culprit, please? One clue: SER is trying to open the config file because when I rename it, it errors out. But when it opens the file, it just hangs. I have even tried inserting random text, and it still hangs. So it appears to not be parsing the text? machine:/usr/local/etc/ser # machine:/usr/local/etc/ser # mv ser.cfg ser.bak machine:/usr/local/etc/ser # ser ERROR: loading config file(/usr/local/etc/ser/ser.cfg): No such file or directory machine:/usr/local/etc/ser # mv ser.bak ser.cfg machine:/usr/local/etc/ser # ser

RE: [Serusers] Problem with ACK

by Jiri Kuthan

Maybe an error in your script. you obviously tried to send a reply using sl_send_reply in response to the ACK. What you really wanted to do was to forward the ACK. -jiri At 11:16 PM 12/23/2004, Amozurrutia Jesus wrote: >I double checked and the ACK are ignored by SER. > >The log file thows this: >Dec 23 13:26:13 sip2 /usr/sbin/ser[21127]: Warning: sl_send_reply: I won't >send a reply for ACK!! > > >Jesus > >-----Original Message----- >From: Greger V.

RE: [Serusers] call log and accounting for forwarded and referredcalls

by Martin Koenig

Hello, welcome to the world of SIP, where the end devices are supposed to be the intelligent network, not the network itself. To really make this and other features ISDN-like features work in the network, one needs a b2bua somewhere. A---SER---B2BUA---SER---B C---^ ^accounting SER A calls from PSTN, B2BUA receives the call, sends INVITE to B B sends 302 to B2BUA. B2BUA sends INVITE in the name of B to C.

[Serusers] audio and video port lost ???

by szj

Hi: Merry Christmas everyone. When I use SER as proxy server, I found a strange problem. My SIP UA have audio and video two media stream. After transfered by SER, the SIP message recieved by my callee UA lost its port information. And I tested it on the sip.iptel.org's SER, this time the audio port info is not lost, but has changed. The video port is still lost( I wonder whether this is caused by NAT). My SER is located in the same private network, why the SER lost the audio and video port info while other info is untouched ????

[Serusers] Need Help with SER

by Abid Mirza

Hi First happy holidays to all, I have setup SER Proxy and working fine as long as I used the URI of type User(a)mydomain.com. Now I want to assign each user an ID of 7471234 which they have to prefix with * (e.g *7471234) to call other user. Lets say UserA with with number 7471234 wants to dial UserB with Tel # 7472222 dials *7472222 and gets connected as long as the UserB is registered with my SER Proxy. If not 404 msg is sent UserA. if UserA dial a PSTN numbe either using + & CounryCode & Number, or 00 & CounryCode & Number, & or 011 & CounryCode & Number, they get forwarded to my Asterisk Server. Please help me identify what should I use the Aliases Table or Subscriber Table or DNS NAPTR to map uri to Number (eg 7471234 maps to UserA(a)mydomain.com). Thanks in Advance, Merry Xmas and Happy New Year! Abid Mirza ===== Abid A. Mirza Bits & Byte Tech., Inc. 146 West 29 Street , 10 Fl.
