hello friends i have two ser proxies *.*.*.18 -- number is 36105 *.*.*.19 -- number is 214103 iam forwarding from *.*.*.19 to *.*.*.18 with iam using the xlite as my user agents but when i try to call from 214103 to 36105 for few seconds it says it s trying but afterwards it says it user not found ser.cfg of *.*.*.19 is as follows ******************************************************* # $Id: nathelper.cfg,v 1.1.2.1 2003/11/24 14:47:18 janakj Exp $ # # simple quick-start config script including nathelper support # This default script includes nathelper support.
