Simulating Call on PRI

Go to solution

I implemented a 2821 voice gateway so we could test our PRI connectivity to our provider. We do not have our call manager server or phones yet, but wondered if I could simulate a call directly from the router itself. Please let me know if this is possible.

Thank you in advance.

Hi

Yes, it's possible.

You'll need to configure the PRI controller as you would for a CME type install.

Boot it up, and if you have the correct hardware you should see a T1 or E1 controller.

If you don't see a controller, and you have a T1/E1 type, you may need to enter something like:

card type e1 0 0                  <--- or t1, whatever's appropriate

then:

isdn switch-type xxx (whatever you use locally)

controller e1

pri-group timeslots 1-30

(no 'service mgcp' means it will terminate locally)

You may need to set crc off, or whatever else you would do for a local PRI.

Do a show isdn status, to verify you have MULTIPLE_FRAME_ESTABLISHED

If you do, then create a dial-peer to use the PRI:

dial-peer voice 101 pots

destination-pattern 9T

port 0/0/0:15

Then you can this command to start a test call:

csim start

Hi

You are getting :   Cause i = 0x80A2 - No circuit/channel available

In the UK, this typically means:

1) We're running a fractional PRI, and have tried to use a channel we ain't paying for... so need to reconfig the pri-group. Not so common elsewhere.. If you suspect that's the case, there's a command to change the b-channel selection order to use channel 1 first. - isdn bchan-number-order asc

2) SP hasn't enabled the circuit. If we get a new circuit, we usually have to phone up the SP who will then enable it.


Regards

Aaron
