Hi, I have been trying for a while the configuration of a VOIP-GSM gateway that I have bought but the registration fails every time. Error at Freeswitch console 2017-06-27 16:27:10.191913 [WARNING] sofia_reg.c:2906 Can't find user [*testadmin@192.168.2.71 <testadmin@192.168.2.71>*] from *192.168.2.69* You must define a domain called '192.168.2.71' in your directory and add a user with the id="*testadmin*" attribute and you must configure your device to use the proper domain in it's authentication credentials. 2017-06-27 16:27:14.071916 [ERR] sofia_reg.c:2447 MySIP Failed Registration with status Request Timeout [408]. failure #1 2017-06-27 16:27:14.111913 [WARNING] sofia_reg.c:505 MySIP Failed Registration [408], setting retry to 30 seconds. Here *'192.168.2.71*' is the local IP of the Freeswitch server and *192.168.2.69* that of the gateway attached to the LAN port of the Freeswitch server. I have put SIP UserID in the gateway admin panel as "*testadmin*" alongwith its passoword. my external SIP profile is as follows: <include> <gateway name="MySIP"> <param name="username" value="testadmin"/> <param name="realm" value="192.168.2.69"/> <param name="from-user" value="testadmin"/> <param name="from-domain" value="192.168.2.69"/> <param name="password" value="****"/> <param name="extension" value="5888"/> <param name="proxy" value="192.168.2.69"/> <param name="expire-seconds" value="120"/> <param name="register" value="true"/> <param name="caller-id-in-from" value="true"/> </gateway> I have tried number of permutations and combinations but the gateway is not getting registered.
