Re: [Serusers] Messenger5.0 481 Error continued
by Jiri Kuthan 30 Oct '03

That's a one-way trick to make 5.0 accept 4.7's instant messages. There is no way to make 4.7 or other standard-based implementation understand 5.0's proprietary messaing model (sending INVITEs to establish a messaging session). -jiri At 04:05 PM 10/28/2003, Rork, Joseph (J.P.) wrote: >I've followed the instructions: >Attention: instant messaging model has changed from 4.7 to 5.0 dramatically and in a non-standard way. 5.0 takes session establishement using INVITE and drops out-of-… [View More]

[Serusers] cisco phone domain
by Daniel Medina 29 Oct '03

29 Oct '03

Hi, We've just installed ser we've noticed that when placing a call from a Cisco IP phone the "From:" is set to "username(a)serserver.domain.com" rather than the expected "username(a)domain.com". Other SIP clients (we've tested with MS Messenger) don't exhibit this problem. At first we thought ser was re-writing this, but ngrep revealed that to not be the case (the phone was actually sending this information). Inserting "rewritehost("domain.com")" into the config didn't seem to alter … [View More]

Re: [Serusers] SIP and NAT Traversal | How To
by Jiri Kuthan 29 Oct '03

29 Oct '03

I think there is a more appealing case, which is getting clients of a public SIP service behind any NATs. an internal SER version does exactly that along with rtpproxy -- feel free to try it out with our public SIP service. It will certainly show up in stable release some day. -jiri At 03:12 PM 10/29/2003, dhiraj.2.bhuyan(a)bt.com wrote: >Hello List, > >SIP and NAT - this issue has been raised on numerous occassions.

[Serusers] reuse of existing tcp connection

i'm behind gprs service that doesn't allow any incoming udp packets or establishment of inbound tcp connections. when i register, a tcp connection is established between my sip ua and ser. if there is an existing tcp connection open between sip ua and ser, is ser supposed to reuse it for all incoming sip traffic, such as subscribes and notifies? -- juha

[Serusers] SIP and NAT Traversal | How To

29 Oct '03

Hello List, SIP and NAT - this issue has been raised on numerous occassions. I finally got a small working demo for SIP Instant Messaging through a NAT gateway (next on the list is to try it with some RTP traffic). I am using "siproxd" http://sourceforge.net/projects/siproxd on the NAT gateway. Siproxd is an proxy/masquerading daemon for the SIP protocol. It allows SIP clients to work behind an IP masquerading firewall or router. Demo setup - [UA1] <------> [siproxd/NAT Gateway]<----… [View More]

listen=0.0.0.0 is not advicable -- it prints 0.0.0.0 in Via, which makes many UASs unable to respond to it. -jiri At 10:48 PM 10/28/2003, David Quenzler wrote: >SER Team, > >Working with two Windows Messenger clients that don not show as 'online' to >each other using 'listen=0.0.0.0' > >On a two node cluster, I have SER running with listen=0.0.0.0 and the mysql >module.

SER Team, Working with two Windows Messenger clients that don not show as 'online' to each other using 'listen=0.0.0.0' On a two node cluster, I have SER running with listen=0.0.0.0 and the mysql module. One node has the clientIP, the other node is on warm standby. Clients connect to a movable IP, which SER picks up as needed Client wants to talk to his buddy +========================+ Client sends a SUBSCRIBE notice to the SER server via the movable IP A different, valid, non-movable SER … [View More]
