Hello,
I am using an x-lite softphone to register with my SIP domain,
(a) Without an outbound proxy - Registration is successful and takes about 3 seconds (b) With an outbound proxy - Registration is successful but takes nearly 15 seconds I briefly describe below the sequence of SIP messages while using the outbound proxy
Register softphone -> proxy Register proxy -> SIP server Register softphone -> proxy 407 Proxy authentication reqd. SIP server -> proxy Register softphone -> proxy 407 Proxy authentication reqd. proxy -> softphone Register softphone -> proxy (With Digest response) Register proxy -> SIP server (With Digest response) 200 OK Sip server -> proxy Register softphone -> proxy (With Digest response)
I am attaching a log with wireshark captures that show SIP messages exchanged between the SIP server,SIP proxy and the x-lite softphone. The log shows several messages being duplicated (REGISTER, 200 OK)
1) Why does the softphone continue to send REGISTER messages after receiving a 200 OK response ? (almost 15 repetitions of REGISTER after receiving 200 OK)
2) What is the reason for the delay in registration times with/without the proxy ?
Thanks and Regards, Vikram.

Hello,
Here is some more information from wireshark,
"No.","Time","Source","Destination","Protocol","Info" "1","0.000000","x_lite_softphone","SIP_proxy","SIP","Request: REGISTER sip:SIP_server" "2","0.000012","x_lite_softphone","SIP_proxy","SIP","Request: REGISTER sip:SIP_server" "5","0.818876","SIP_proxy","SIP_server","SIP","Request: REGISTER sip:SIP_server" "6","0.818886","SIP_proxy","SIP_server","SIP","Request: REGISTER sip:SIP_server" "7","0.824475","SIP_server","SIP_proxy","SIP","Status: 200 OK (1 bindings)" "15","2.635788","SIP_proxy","x_lite_softphone","SIP","Status: 200 OK (1 bindings)"
Looking at the timestamps for these SIP messages - It takes the proxy 0.8s to relay REGISTER request to SIP server - It takes the proxy 1.8s to relay 200 OK to the softphone
These time durations appear to be very long. What are the expected time durations for these relay times? What might be causing relay times to be so large ?
Thanks in advance.
Regards, Vikram.
Hello,
I am using an x-lite softphone to register with my SIP domain,
(a) Without an outbound proxy - Registration is successful and takes about 3 seconds (b) With an outbound proxy - Registration is successful but takes nearly 15 seconds I briefly describe below the sequence of SIP messages while using the outbound proxy
Register softphone -> proxy Register proxy -> SIP server Register softphone -> proxy 407 Proxy authentication reqd. SIP server -> proxy Register softphone -> proxy 407 Proxy authentication reqd. proxy -> softphone Register softphone -> proxy (With Digest response) Register proxy -> SIP server (With Digest response) 200 OK Sip server -> proxy Register softphone -> proxy (With Digest response)
I am attaching a log with wireshark captures that show SIP messages exchanged between the SIP server,SIP proxy and the x-lite softphone. The log shows several messages being duplicated (REGISTER, 200 OK)
- Why does the softphone continue to send REGISTER messages after
receiving a 200 OK response ? (almost 15 repetitions of REGISTER after receiving 200 OK)
- What is the reason for the delay in registration times with/without
the proxy ?
Thanks and Regards, Vikram.

Hello,
what version are you using? Do you have big traffic on it?
Usual delays are coming from: - slow dns - slow database - lot of debugging with non-asynchronous syslog - bad config file
You can use benchmark module to get executing time of parts in configuration file. If you can share config, some people here on mailing list may have some hints about the cause.
Cheers, Daniel

Daniel,
Thank you for your response.

I am using version 1.5, and there isn't much traffic.
Usual delays are coming from:
- lot of debugging with non-asynchronous syslog
This was a very useful tip. Turns out that HD access times were very poor
hdparm -t /dev/hda output Timing buffered disk reads: 12 MB in 3.48 seconds = 3.45 MB/sec
I tested registration times after setting debug=0 in the kamailio.cfg file, and registrations were much quicker. I plan on working around this issue by switching to AHCI mode from IDE mode.
Once again, Thank you very much. Vikram.

Hello,
I was able to fix the problem, by enabling AHCI in the BIOS and rebuilding initrd with the ahci driver. Instructions in link below
http://serverfault.com/questions/68793/enabling-ahci-in-rhel5-post-install
Current hdparm -t /dev/sda output Timing buffered disk reads: 182 MB in 3.02 seconds = 60.29 MB/sec
Thanks for all the help. Vikram.
