Regards,<br><br>I have a debian (etch - kernel 2.6.18) server with openser 1.1.0-9-etch1 installed and Asterisk 1.4.6. To admin openser, I&#39;m using openseradmin 0.3 and Asterisk-GUI (Rev. 1203) to admin Asterisk.<br><br>
Openser service works fine to make calls between users (Linksys phones, ATA phones, Sipura phones, etc.) and I installed Asterisk to use VoiceMail,&nbsp; Call Queues, Conferencing,&nbsp; Voice Menus, Calls redirections and PSTN GW functions. NOTE: I can hear only Asterisk VoiceMail, but I&#39;m still working to openser-asterisk integration. For me, who I am a new Linux user,&nbsp; It&#39;s&nbsp; hard but not impossible. 
<br><br>I want to configure call restrictions between openser VoIP groups at the same domain.<br><br>For example:<br><br>I have an IP Network with clients who has remote offices. I&#39;m using openser to connect their offices. Now, I want to use groups to resctric calls between clients.
<br><br>I want to know what&#39;s the best solution to do calls restrictions between groups. <br><br>I must use AVPops, Groups, Asterisk modules, etc ??????<br><br>Can anybody help me?<br><br>PD: I&#39;m sorry for my spanglish.
<br><br>Thanks<br>
