extensions registration

Can we assign static extensions to each of the 24 timeslots on the t1 trunk side.

Re: extensions registration

I'm not familiar with that exact platform, but if it's similar to the TA900 you can assign a separate voice trunk to each timeslot and configure each with a unique DNIS. Dialing that number will send ringing out that specific channel.

T-1 RBS/CAS connections don't exactly have "registration" in the sense that SIP endpoints do.

Re: extensions registration

Actually i have a telephone simulator (Ameritec PCM/VF call analyzer) plugged into my NetVanta 644 through my t1 connection, and a ethernet cable from my gigabit-ethernet port  that goes into a switch connected to a VoIP server and VoIP phone.

I can make calls from my Ameritec to my VoIP phone by dialing the VoIP phone extension. But to call from my VoIP phone to the Ameritec i need an extension and the problem is that the Ameritec doesn't have an extension or a number it is a phone simulator, so i am trying to find a way to give an extension to the t1 trunk, so when the adtran receive a call from a number it puts it on the t1 line.

Re: extensions registration

Try something like this, assuming that the T1 voice trunk is T01. Dialing 4444 should connect to the simulator.

!

voice grouped-trunk T1-test

trunk T01

accept 4444

!

If this doesn't work, paste your configuration.

If you want individual extensions for each channel, you'll need to create 24 voice trunks, each connected to one channel (tdm-group), then build 24 grouped-trunks associated with the voice trunks and each having a unique extension.

The usual way to do this is either with a PRI that can dynamically route the extensions, or with a single RBS trunk and DIDs where the extension digits are sent to the PBX as DTMF. The PBX then routes the calls based on received digits. If you'll be connecting to a channel bank with a unique extension per channel, then you'll need the individual trunks and extensions.

I'm not familiar with your simulator and whether it can detect and display DTMF, or act as a PRI. If it can, then you can play with the various options.

Re: extensions registration

network topology.png

this is my network topology.

I dont have a PBX for the Ameritec. This is why i am trying to find a way to pass the call without a PBX. I am trying to find if it is possible.

you said to build 24 grouped-trunks associated with the voice trunks and each having a unique extension. This might be the solution, how can i give unique extension to the trunks as you said.

thanks

Re: extensions registration

OK, because you have a call analyzer and not a PBX, your device doesn't route calls in the normal way. Try the following in your config:

interface t1 0/1

  tdm-group 1 timeslots 1 speed 64

  tdm-group 2 timeslots 2 speed 64

  tdm-group 3 timeslots 3 speed 64

  tdm-group 4 timeslots 4 speed 64

  tdm-group 5 timeslots 5 speed 64

  tdm-group 6 timeslots 6 speed 64

  tdm-group 7 timeslots 7 speed 64

  tdm-group 8 timeslots 8 speed 64

  tdm-group 9 timeslots 9 speed 64

  tdm-group 10 timeslots 10 speed 64

  tdm-group 11 timeslots 11 speed 64

  tdm-group 12 timeslots 12 speed 64

  tdm-group 13 timeslots 13 speed 64

  tdm-group 14 timeslots 14 speed 64

  tdm-group 15 timeslots 15 speed 64

  tdm-group 16 timeslots 16 speed 64

  tdm-group 17 timeslots 17 speed 64

Now, if you dial any 4-digit extension between 4000 and 4999 it should show up on your call analyzer. For example, calling 4123 should look like:

>HW4123

You'll need to determine how to tell the AM8a to answer the call. I'm not sure that it's capable of doing so. It's primarily a piece of test equipment to analyze traffic and not really intended to be used as a telephone. I found its operation manual online here: http://dedisol.unsads.com/~squalyl/kurteries/manuals/Other/AMERITEC%20AM8a%20PCM%20VF%20Instruction....

You might want to get a channel bank or better yet, a PBX with a T1 PRI/RBS interface for your lab.

Re: extensions registration

I tried but the call didn't go through. It may be the fact that there is no PBX.

Re: extensions registration

Did you see a display on the analyzer similar to >HW4123 ?

I don't think the call will "go through" but the simulator should display the attempt.

What is the output from "debug voice verbose" when you place a call to the simulator? Does it route to T02?

Re: extensions registration

I didn't see a display >HW4123 on the analyzer.

VoIP phone: 192.168.184.246

VoIP server: 192.168.184.250

Adtran interface: 192.168.184.225

I had this result:

-the extension 4500 registered

-When an <Option request> is sent from the VoIP server to the Adtran it reply with the status <501 not Implemented>

pastedImage_0.png

-When i dial the extension 4500 on the VoIP phone,

first the VoIP phone sends a SIP invite.

Second the VoIP phone receive a <401 Unauthorized> message

Third when the VoIP phone send another  SIP invite, it receives a <not acceptable here> by the VoIP server and it shows and i cans see on the VoIP phone screen <not acceptable here 4500>
