[Serusers] MWI - message waiting indication

hello, I read http://www.voip-info.org/tiki-index.php?page=Asterisk+at+large anybody could tell me more about this ? Is it available with ARA ? Regards Harry Method 3 Q: If you have your SIP phones registered with SER but your voicemail is handled by asterisk, how do you get the MWI (Message Waiting Indicator) light to function on the phone? A: In sip.conf create a section pointing at your SER router. [ser] type=friend ; We allow incoming and outgoing calls. Use peer if you are only doing MWI context=ser ; This is the context incoming calls land in host=ser.server.tld ; This is the hostname or IP address of your SER server fromdomain=ser.server.rld ; This is your SER_DOMAIN insecure=very ; This allows incoming calls from the phones routing through ser to be passed into asterisk mailbox=user@context ; This is where you list the voicemail boxes to monitor This tells asterisk that if a voicemail comes in to "user" then it needs to send a SIP NOTIFY message to the "ser.server.tld" phone. Well this is all well and good except how does SER deliver this NOTIFY to the phones? First thing is that you need to make a tiny change to the asterisk code to pass the mailbox user in the SIP NOTIFY packet. --- channels/chan_sip.c.orig Thu Jul 14 12:03:18 2005 +++ channels/chan_sip.c Thu Jul 14 12:05:26 2005 @@ -9710,6 +9710,7 @@ /* Called with peerl lock, but releases it */ struct sip_pvt *p; int newmsgs, oldmsgs; + char *s; /* Check for messages */ ast_app_messagecount(peer->mailbox, &newmsgs, &oldmsgs); @@ -9735,6 +9736,10 @@ /* Recalculate our side, and recalculate Call ID */ if (ast_sip_ouraddrfor(&p->sa.sin_addr,&p->ourip)) memcpy(&p->ourip, &__ourip, sizeof(p->ourip)); + strcpy(p -> username, peer -> mailbox); /* Username = Mailbox name */ + s = strchr(p -> username, '@'); /* Remove the context part */ + if (s != NULL) + *s = 0; build_via(p, p->via, sizeof(p->via)); build_callid(p->callid, sizeof(p->callid), p->ourip, p->fromdomain); /* Send MWI */ After this patch is applied, the MWI NOTIFY messages coming from asterisk will have the URI user(a)ser.server.tld. This can be then routed with ser to the correct phone with normal SER routing rules. ie. SER does a lookup("location") and then a t_relay(). I don't believe this patch should effect any non-ser controlled sip phones. For me, this method was a lot easier then Method 2 listed above. You can add as may mailbox's as you like into the mailbox= line in the asterisk sip.conf file. One possible problem is if you have a mailbox called 1000@cx1 and another called 1000@cx2, this patch will make the MWI indicator light up for phone 1000(a)ser.server.tld when either mailbox gets a message. A simple modification to the patch and SER could be used to handle multiple contexts if required however this simplification is sufficient for me. ___________________________________________________________________________ Appel audio GRATUIT partout dans le monde avec le nouveau Yahoo!
