Hi all, I have decided to send this e-mail because you are the
developer of Asterisk . We are developing a phone
system using Asterisk as the VOIP gateway with 1 t410 PRI card and Sip Express
Router as the proxy server but we have a problem. Our phone system setup like
this: SIP phones------------>SER--------------->Asterisk---------------->PSTN(PRI
connected to NORTEL DES 100 switch) transfer the call to Sip
Express router then to the phone. So when there is a call from
the pstn through asterisk and the phone is busy or the number is
invalid ,asterisk tells the switch that the call is going on and the
phone is ringing while it is not the case. I would like to find a way of informing Asterisk that the
call is progressing or something like that, not ringing until it gets the
correct message from SER . I am using Asterisk
CVS-03/22/04-15:45:54 on Red Hat 9 and Sip Express Router version 12 on
Red Hat 9. I tried to use PRI_causes
but still the problem is there. Any idea on how I can
solve this problem? Thanks |
