908 fails to receive calls

Jump to solution

Hello everyone, 

I'm new to the TDM world even though I've worked in the SIP world just for a few years. 

The company I work for uses a lot of Adtran devices (900 series at customer premise)

We have an Adtran 908 at a customer premise.  This device is connected to our network via IP via vpn  (No NAT).  I have access to both SSH and web gui.

It was previously configured and working but hasn't been used in 6 months or more.  I can see that the device is set to peer to the sip server and shows ready. When I call a number that is directed to it,  the adtran receives the call, but seems to redirect it back to our Sonus.

Suggestions?  I'm unsure what information is needed as I'm so green to Adtran.

Re: 908 fails to receive calls

Jump to solution

Your issue is with the SIP server initiating the call and not with the analog FXS station.

Generally, a call is initiated with a SIP INVITE message having the call details such as calling and called number, IP and port for the RTP session (SDP), and other data related to the call.

Your provider, however, first sends an OPTIONS message to determine if your device is alive and ready to accept a call. It's kind of like asking "Are you there?" before delivering a message. OPTIONS can also query such things as SDP capabilities and the like, but this doesn't seem to be the case here. If the sender gets a response that indicates the call will fail, or gets no response at all, then no INVITE is ever sent.

Looking at the debug, you receive the OPTIONS message and immediately respond with an OK stating your capabilities including that you can accept an INVITE.

Apparently, the SIP server at 192.192.192.99 never receives your reply. Therefore it never sends the INVITE. Seeing as the OPTIONS messages are received every 15 seconds exactly, my guess is that the sending server is not receiving your replies and is set to retry three times at 15-second intervals, then give up.

This could be an IP routing issue, a firewall rule somewhere, or simply broken behavior on the part SIP sender. Further examination of your configuration indicates something odd. You have:

!

ip route 0.0.0.0 0.0.0.0 10.0.250.1

ip route 0.0.0.0 0.0.0.0 71.41.86.201

ip route 0.0.0.0 0.0.0.0 96.252.180.1

!

Yet the only connected IP interface is eth 0/1 which is in the 10.0.250.0/24 space. Therefore your second two default routes should be removed.

However, 10.0.250.0/24 is a private address. You say there's a VPN between it and your network with no NAT. Is the SIP server "sonus" also on your network with no NAT, or does it traverse an external NAT to go to the Internet to reach "sonus"? You will want to avoid NAT between the Adtran TA900 and the SIP server.

At any rate, if the response to the OPTIONS message isn't received and processed, then the INVITE will also almost certainly fail.

Troubleshoot the path from your TA908 back to SIP server "sonus" and you'll probably find the issue.

Where is the call supposed to go? Is there a PRI connected to it? A SIP PBX? Individual analog users? It could be that the call is reaching the customer PBX and that is hairpinning the call back. Can the customer place outbound calls OK?

A sanitized configuration (remove passwords and public IP info) and the results of "debug voice verbose" when a call is placed would be useful.

Here you go..

Call is supposed to go to a FXS port (analog user).

Unsure about outbound calls.  I have a call into the on premise to test outbound calls.  Awaiting response from them.

Here is a sanitized copy of the config.

Re: 908 fails to receive calls

Jump to solution

If nothing happened during the debug voice verbose, it sounds like the call either never hit the TA900 or the TA900 isn't accepting its SIP.

The SIP capture is an options message and doesn't look like it is necessarily related to your call.

Does "debug sip stack messages" show an INVITE message?

Also, while not related to this specific problem, your dial plan could use some tweaks. To avoid potential issues, you probably want to change the following to "local" instead of "always-permitted".

voice dial-plan 8 always-permitted 511

voice dial-plan 9 always-permitted 411

voice dial-plan 10 always-permitted 1-411

voice dial-plan 11 always-permitted 555-1212

always-permitted is for emergency calls.

And you should have:

voice dial-plan 2 always-permitted 911

​In addition, 1-844-NXX-XXXX and 1-833-NXX-XXXX are now valid toll-free patterns.

Re: 908 fails to receive calls

Jump to solution

Your issue is with the SIP server initiating the call and not with the analog FXS station.

Generally, a call is initiated with a SIP INVITE message having the call details such as calling and called number, IP and port for the RTP session (SDP), and other data related to the call.

Your provider, however, first sends an OPTIONS message to determine if your device is alive and ready to accept a call. It's kind of like asking "Are you there?" before delivering a message. OPTIONS can also query such things as SDP capabilities and the like, but this doesn't seem to be the case here. If the sender gets a response that indicates the call will fail, or gets no response at all, then no INVITE is ever sent.

Looking at the debug, you receive the OPTIONS message and immediately respond with an OK stating your capabilities including that you can accept an INVITE.

Apparently, the SIP server at 192.192.192.99 never receives your reply. Therefore it never sends the INVITE. Seeing as the OPTIONS messages are received every 15 seconds exactly, my guess is that the sending server is not receiving your replies and is set to retry three times at 15-second intervals, then give up.

This could be an IP routing issue, a firewall rule somewhere, or simply broken behavior on the part SIP sender. Further examination of your configuration indicates something odd. You have:

!

ip route 0.0.0.0 0.0.0.0 10.0.250.1

ip route 0.0.0.0 0.0.0.0 71.41.86.201

ip route 0.0.0.0 0.0.0.0 96.252.180.1

!

Yet the only connected IP interface is eth 0/1 which is in the 10.0.250.0/24 space. Therefore your second two default routes should be removed.

However, 10.0.250.0/24 is a private address. You say there's a VPN between it and your network with no NAT. Is the SIP server "sonus" also on your network with no NAT, or does it traverse an external NAT to go to the Internet to reach "sonus"? You will want to avoid NAT between the Adtran TA900 and the SIP server.

At any rate, if the response to the OPTIONS message isn't received and processed, then the INVITE will also almost certainly fail.

Troubleshoot the path from your TA908 back to SIP server "sonus" and you'll probably find the issue.

Re: 908 fails to receive calls

I've removed the additional default routes and I've verified two way connectivity between the 908 and the Sonus.  Also, I've tripled checked the vpn config, and the routing is without NAT.   (When we deploy a customer device, we reserve the IP space used in the private space within our network and just route the packets.   We mainly did this before net neutrality was a thing, and now its even more important. )

BTW, is there a guide or a tree to lookup all the CLI commands for the 900 series and how they are used?

OK, next step would be to determine why the Sonus is unhappy with (or ignoring) the 200OK responses to the OPTIONS messages, or get it to not do the OPTIONS thing and just send an INVITE.

The problem seems to be that the Sonus doesn't see (or doesn't like) the response to its OPTIONS query and thus never sets up the call.

Yep, already working withe Sonus engineer and explained to him that the invite doesn't seem to be sent.   

For the Bible, have things changed much from v11 and v12?  Looks like the latest this 908 supports is v11.

Most of the commands are the same. There are some new ones that are only in R12. A couple of years ago they tweaked the use of the "ip" keyword to differentiate between IPv4 and IPv6. Mostly, the "ip" was removed from commands that would apply equally to v4 and v6 and added where the specific version needed to be specified. This was mostly within the various flavors of R10.

When you upgrade, on the first reboot the configuration is parsed and tweaked as needed to be compatible with the new version. This works really well so no issues. However, if you ever need to roll back to an older version and the configuration was automatically modified, things will break. An archive utility like RANCID is your friend.

I also recommend that you archive any Adtran documentation and firmware that you use locally as they have become pretty aggressive about removing older versions from the website.

Understood thank you!

Well, still no luck on my side.

Is there any kind of step by step tutorial to configure one of these 900 series from scratch as an peering ATA (no registration)?.   I feel as if I'm missing something and it'd do me some good to work with this as much as I can.

Not per se that I'm aware of. Basic idea, set up a voice trunk type SIP with the other side as the SIP server (ip or hostname). Don't configure registration. Do the same on the other side with the ip of the TA900. You can do two of them back-to-back or set one up to peer with your SBC.

Then use the grouped-trunk to configure the digit patterns to send to the other side.

For more than one endpoint, build multiple trunks.

The GUI is easier initially to do much of this, but the CLI is more powerful. You can use the GUI to build a simple configuration and then use the CLI to see what was done and modify it. If you're going to be working with these devices a lot, learn to do everything in the CLI. Learning curve isn't that steep.

Re: 908 fails to receive calls

Jump to solution

Just wanted to let you know we used a different sip server (our legacy one) and everything worked fine.  Just updated the voip trunk to reflect the different ip, applied and rebooted and voila, magic.   Go figure. 

Thanks so much for helping a new guy.

Now that the fire is out, going to put one on a bench and set it up from scratch from the CLI.
