There is nothing to improve in SER as long the communication was established. In the case a NAT would be involved you would need either a RTP relay (rtpproxy, media proxy) or in some cases just a STUN server (depending on SIP clients and NAT type).

No, there was no NAT involved, both phones were in the same LAN. With bad comunication I mean bad audio (with eco) and with lots of moments with no audio at all.
Try to force the SIP clients to use some other audio codec (if they support more than one) -- maybe one has a broken implementation of the codec chosen for communication.
And in the same LAN and in the same conditions, but with Asterisk, the comunication was perfect.
I do not know much about asterisk, it may do some media correction or codecs translation.

Is there any configuration changes that I can make to inprove SER?

what you mean by communication was bad? The audio quality? The signaling?
SER doesn't deal with audio stream at all, just with the signaling part. Is there any NAT involved?

Hi I tried two SIP Phones Zyxel Prestige 2000 W with SER and the comunication was very bad, even in a second test with SIP software client and a Zyxel phone, the comunication wasnt good, then I tried the same phones and software with the Asterisk server and the comunication was perfect, can I configure SER to have a better performance in the comunication? Does anyone experienced a problem like this?
