Hello: Has anyone on this list had to configure hairpinning on a Cisco gateway running IOS 12.2 or 12.3 and using a PRI for connectivity to the PSTN? If so could you tell me how it is done? I'm told this is the source of my call transfer problems and yet I cannot find clear instructions for how the configuration is done. Thanks,Steve -- ISC Ne...

Hi: Currently we encounter a problem where OpenStack may forget or misconfig the bridge hairpin setting, and will cause some unexpected behavior [1]. Although this bug is marked fixed, but if we manually restart the vm by virsh will also trigger the problem. And because the bridge interface is created and managed by libvirt, we are considering move the hairpin configuration to libvirt....

...RedHat 9.0 I frequently have the need to redirect calls that come in on a DiD provisioned by my ITSP, back to the ITSP so that they can terminate the call on the PSTN. For example when an external call comes in, I often have to send it to a cell phone. I believe that this is referred to as "hairpinning" the call. I do this by answering the incoming call and then I use a simple "dial" command to send it back to my ISTP using a SIP or IAX channel and the ITSP terminates it on the cell phone. One of my main goals is to keep my Asterisk box out of the media path and let the ITS...

...'nat' detection. I suppose this means the SBC listens from where it is getting RTP data and then replies to that ip. As long as the asterisk is initiating the call this is fine, the asterisk start sending RTP to the media IP of the SBC and the SBC is sending media back. Now I want to do a hairpin call, simulating call forward on no answer (yes this is the situation I observed the problem first) So incoming AND outgoing calls are via SBC. exten => destination,1,Progress() exten => same,n,Playtones(ring) exten => same,n,Wait(5) exten => same,n,Dial(PJSIP/sip:external at sbc) Wh...

...aborates with an adjacent, external bridge to provide distributed bridging support between multiple virtual end stations and external networks. The VEPA collaborates by forwarding all station-originated frames to the adjacent bridge for frame processing and frame relay (including so-called 'hairpin' forwarding) and by steering and replicating frames received from the VEPA uplink to the appropriate destinations. A VEPA may be implemented in software or in conjunction with embedded hardware. In particular, the patch extends the Linux Ethernet bridge utilities to configure a bridge to ac...

Hi Joshua > The "rtp_keepalive" option can be used to have the RTP stack send an > RTP packet out. Try that and see what happens. Once again 'bullseye' that fixed the problem. Thank you!

...remely useful but as others have found out before me requires significant changes not only to macvlan but also to the common transmit path. I've seen one panic during testing this that I still need to track down, but it generally does what is advertised. I've tested VEPA operation with the hairpin support added to the bridge driver by Anna Fischer. My current plan is to submit this for inclusion in 2.6.33 when people are happy with it and I tracked down any remaining bugs, and possibly to do the communication with the lower device one release later.
