<DIV>I know that the syntax for registration is </DIV>
<DIV> </DIV>
<DIV> register => user[:secret[:authuser]]@host[:port][/contact]</DIV>
<DIV> </DIV>
<DIV>but then most of the TSP allow me to register without specifying the <contact> <BR>field. This allows me to use the <s> extension to process all incoming calls.<BR> <BR>Now, with this specific TSP (phonesystems.net) registration is succesful only if my Asterisk passes a contact number, any number at that, as long as it's <BR>different from the <user> field. </DIV>
<DIV> </DIV>
<DIV>Their support line told me they also use ASTERISK.</DIV>
<DIV> </DIV>
<DIV>My questions are:</DIV>
<DIV> 1) what type of set-up in the service provider's ASTERISK box requires that a <BR> contact number be provided by the registering box?<BR> 2) while I can process the incoming calls from all other TSPs using the "s" <BR> extension, therefore needing only one set of instructions common to all,<BR> the incoming call processing instructions for this TSP have to use the<BR> <contact> as an extension, hence unnecessary code duplication. <BR> Is there a way around it except for using extension <contact> also for the <BR> other TSPs?</DIV>
<DIV>Thanks for your help.</DIV>
