Inbound SRST call backs

[hutto.txed.net]

Let me see if I can explain what I am trying to do, with my SRST.  I have configured Device pools and Route Patterns that use the SRST router to call 911 from ip phones in the class rooms.  This is working Great, I have a hard line to the phone port on the SRST router setup so when a phone in the school dials 911 they all go through the hard line correctly sending 911 services to the correct location, no problem here.  The problem is when we have a 911 hang up, and 911 operator calls back they dial the hard line number that is attached to the router and they get no answer or busy and they send some one out all the time.  My question, is there a way to forward call backs from this line to a internal extension manned by a receptionist or a live body.  I am running Call Manager 7.1.  I hope this makes sense and any help will be great.

What is the "hard line" is this an FXO trunk line? What protocol are you using to control the GW, i.e. MGCP/H323/SIP?

It is an FXS port, and I am using h323/

FXS line connected to telco for e911?  Is it FXS/DID with DID number riding on it?  Are is there specific number for each circuit and possibly a FXO circuit?

Never mind I just looked at the back of the router,  It is a fxo port and I have a dedicated DID line coming into it, from the telco.

[Chris Deren]

Then what you do is configure the port with plar config "connection plar opx XXXX" where XXXX is the destination you want the call go to.

HTH, please rate all useful posts!

It is not working, here is my router config.  it is a 2800 router.  The 5493 is the extension I want it to ring at.

So, what is extension 5493 defined as on CUCM?

Does the CSS applied to the H323 on CUCM have access to the parition assigned ot 5943? 

Chris

[hutto.txed.net]

Not sure what you ment by definded on CUCM.  Partitions? CSS?, How can I tell what CSS is applied to the H323 on CUCM.  I did not configure this router, it was done a while back.

[Chris Deren]

Your GW configuration points to DN 5493, what is that DN in CUCM defined as?

When the call arrives to this GW, via voip dial-peer it redirects the call to CUCM, CUCM has the GW defined as H323 GW with name being the IP address of the GW, it has Calling Search Space applied to it. You need to ensure that the applied CSS lists partition that is assigned to the 5493 extension.

HTH,

Chris
