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

"15","2.635788","SIP_proxy","x_lite_softphone","SIP","Status:

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)
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.
