Hi Ali.

    As far as i know you must put the "User-Agent" field for the asymmetric client. I have it working without problems here.

    Good luck!

Regards,

Ricardo.-

Hi,

I have been using ser with mediaproxy for more than a year without any major issue.

I have couple of asymmetric UAs, and i'm not able to call them most of the time. i noticed in my ser.cfg following lines.

My ser.cfg

===========================

modparam("mediaproxy","sip_asymmetrics","/usr/local/etc/ser/sip-clients")
modparam("mediaproxy","rtp_asymmetrics","/usr/local/etc/ser/rtp-clients")
# modparam("mediaproxy","sip_asymmetrics","/usr/local/etc/ser/sip-asymmetric-clients")
# modparam("mediaproxy","rtp_asymmetrics","/usr/local/etc/ser/rtp-asymmetric-clients")

===========================

I have above files in ser folder, and i tried to put user agent in sip-clients file, i don't know if i'm doing it right.

Ii'm still trying to figure it out, what should i put in these sip-clients and rtp-clients files (username? URI ), and how do i know if they are working.
I just put UA 5007860215 and restarted ser and mediaproxy but ngrep are same.

my sip-clients file is as follows:

########### START ##################
# Lines starting with a '#' character or empty lines are ignored.
# Put a User-Agent name or regular expression per line.
# Check is case insensitive.
#
# This file should only list SIP clients that are asymmetric regarding
# the SIP signaling. For clients that are asymmetric regarding the RTP
# media streams, use the equivalent RTP version of this file.
# Clients that are asymmetric for both SIP signaling as well as RTP media
# streams should go in both files.
#

ipDialog SipTone.* #<== what is it?
5007860215

########### END OF FILE############

client sending keep alive message, reason i setup keep alive on my client is becouse they were keep loosing registration, so that problem is solved. Following asymentric client coming through port 50005 and SER sending reply at port 5060.

If i ping my UA with (serctl ping sip:5007860208@ser.mydomain.com) i get following ngrep. It appears that SER has no problem reaching UA at port 50005.
