SIP message problems - retransmit and lost messages
I have an asterisk system in Costa Rica that connects to a SIP provider in Atlanta. Sometimes SIP packets seem get dropped or retransmitted too quickly. In trying to debug this I turned on SIP debug in Asterisk and the SIP provider enabled packet capture on his end. What I saw was me sending an invite, them sending a 100 Trying, me sending a cancel, me sending a retransmit of the cancel, me sending another retransmit of the cancel...

Request Pending retransmitions
...e a SIP 491 Request Pending Response. This happens because I try to place a call on hold using an Invite request rigth before Asterisk sends me a Re-Invite for the same call. I respond to the 491 response with an ACK however for some strange reason Asterisk doesn't accept the ACK and insists on retransmitting the 491 Response. Asterisk replies with the following 491 response: SIP/2.0 491 Request Pending Via: SIP/2.0/UDP 10.110.7.89:5070;branch=z9hG4bK5a668c33f196837c3602266b23b389e0;received=10.110.7.89 From: <sip:30001 at 10.110.7.20:5070>;tag=SIPTester To: <sip:30008 at 10.110.7.20&g...

Slow TCP performance between Windows Vista and Xen PV-on-HVM guest
...or also Windows 7 machine and I am getting really poor TCP performance. When tracing on the network traffic, I can see that no packets are dropped or missing or anything, but what happens is that the Vista machine does not seem to send an ACK back to the Xen guest, and then the Xen guest is doing a retransmit after a while. But this is causing huge delays and SCP, for example, mostly fails completely because of the poor performance. I am thinking that perhaps the problem here could be that the Windows machine is using the delayed ACK mechanism but the Xen guest does not actually send further data so thi...

Asterisk not recognizing ACK from an OK message? Help debuging SIP retransmit problem
...capture a full sip trace. I'll paste it in full below, but I'll give a summary first. It seems that Asterisk is not recognizing the ACK messages that it receives from the Grandstream ATA. This happens only on the ACK that follows the OK that marks a call as established. This makes Asterisk retransmit the OK message 6 times, after which it drops the call (after exactly 20 seconds). The strange thing is that the "branch" parameter of the ACK is different than the branch parameter from the OK it is replying to, however, this seems to be normal behaviour as specified in the RFC for an AC...

Reliability between TCPonly and UDP for tinc?
I agree with the in-effective of TCP transmission, but I wonder if the the UDP packet is dropped, the tinc VPN itself wouldn’t retransmit, and if the upper level application doesn’t handle the packet loss well, will this be the problem? Or the upper level application have very limited tolerance to packet loss(like RDP application, I guess if the packet loss go to certain threshold, the connection will be lost). > On 18 Jun 2017,...

SIP Retransmitting REGISTER message
Hi, I was trying to register a VoIP trunk in Asterisk , where its keep on sending Register message to the server, where I am not getting any response from server. But whereas if i register in Xlite softphone the account is getting registered. I suspect it could be network related issue, but since in softphone it is getting registered from the same network. Any ideas to isolate things would be

Windows 2008r2 guest tcp retransmit hangs
Hi, I'm currently investigating a problem with our windows 2008r2 guest on centos 6 hosts. The issue is that the windows system sometimes sees a SYN packet for a tcp connection but doesn't respond. Three seconds later the retransmitted packet arrives and this time windows decides to proceed normally with the connection. This is with the virtio drivers but I have now switched to the e1000 driver where the problem also occurs but not quite as badly as with virtio which leads me to speculate that the driver isn't really th...

stuck on retransmit
Hi, I have set up the latest code * server, and I'm having problems with the sip phone. I'm using the budgetone. I can receive calls just fine. When I try to place outgoing calls, I can see that the rules get followed fine. But once it dials the analog interface (X100P), it starts retransmitting packets in chan_sip.c:retrans_pkt() any ideaas why this would be? thanks TJ
