PANASONIC NS 1000 trunk-to-trunk calls

PANASONIC NS 1000 trunk-to-trunk calls

PANASONIC NS 1000 trunk-to-trunk calls

(OP)
Hello

I am new to the Panasonic system and I wanted to know if I can do trunk to trunk calls with Panasonic NS 1000 I see my setup below:


When I try to make calls from the Asterisk it gives me the Bad Gateway error.I don't if its something wrong with my configuration but I see all the SIP Trunks being okay for both my Voice provider and the LAN Asterisk.

I don't know if I am missing something but I really cant figure out where I am getting it wrong or may be the Panasonic system doesn't allow trunk to trunk calls.

Please help.

RE: PANASONIC NS 1000 trunk-to-trunk calls

How are you routing the calls between the trunks what are you dialling

RE: PANASONIC NS 1000 trunk-to-trunk calls

@ OBT, good question. Because i too integrated Asterisk to Panasonic both via PRI and via SIP Trunk but found it hard to send calls to Asterisk from Panasonic without first pressing 9 to cease the trunk. Dialing from Asterisk to Panasonic has always been easy - One can dial the extension numbers on Panasonic directly.

I will be glad if he can share how he is routing calls to Asterisk from Panasonic without having to first press "9"

To make calls to the Asterisk via the Extensions yes I press 9 first.Calls from Voice provider to the Asterisk via Panasonic are working no problem .Now my challenge is the part @Otoni said its easy calls from Asterisk to the Voice provider via Panasonic NS1000 every time I try to call I get the Bad Gateway error.I don't know what I am missing now.

Also just you know the Asterisk is a contact center solution I am using with WebRTC with 30 agents.

RE: PANASONIC NS 1000 trunk-to-trunk calls

Are you saying your challenge is " Calling from Panasonic to PSTN via Panasonic?"

And that your main trunk is connected to the Panasonic?

From Asterisk trunk to the main SIP trunk on Panasonic NS 1000.

RE: PANASONIC NS 1000 trunk-to-trunk calls

I have always found that difficult. Its actually easier to have the SIP Trunk on Asterisk and call from Panasonic to PSTN via SIP Trunk on Asterisk. The other way has always proved difficult for me.

RE: PANASONIC NS 1000 trunk-to-trunk calls

The problem is you are trying to go from co to co

If you had 9 on the asterisks dial into disa on the panasonic and get it to dial 9 plus the number it should work as long as you set the correct class of service.

Have you tried to do ip gateway between the two systems instead if ip trunks

RE: PANASONIC NS 1000 trunk-to-trunk calls

@obssystems I don't have the ip gateway license I only have for the SIPGW but well I am still struggling cant call from Asterisk to Panasonic NS1000 even the ext I can t call.Anyone can help.

RE: PANASONIC NS 1000 trunk-to-trunk calls

It is the same licence. Just change it from o of 4 or number of licence on the system to number of license you want as gateway. In pairs of 2 in activation keys

@obtsystem have setup the IPGW as to the Panasonic Manual but still they are OUS see the image

RE: PANASONIC NS 1000 trunk-to-trunk calls

Hello, correct me if i am wrong. My understanding is that you have your SIP Trunk on the KX-NS1000 and you would like to make and receive calls through the same trunk on the Asterisk server. I implemented a somehow similar project for a hospital that had a KX-TDA200 system who capacity and been exhausted and they wanted to go VoIP without overhauling the system (KX-TDA200) that was in place. I installed Asterisk on a Dell T630 with Digium 1TE235BF dual span E1 card. Note that the KX-TDA200 originally had an E1 connection from the Telco. I connected the E1 from the Telco to Port-1 of the Dual span E1 card in the Asterisk server and connected Port-2 to the E1 port on the Panasonic KX-TDA200. Did the configs and routing as per what i thought it should be. What is discovered is that pushing calls from Asterisk to the PSTN trunks connected on the Panasonic was quite a hustle. To this day i did not succeed with it. However it was easier pushing calls from extensions on the KX-TDA200 to the PSTN via trunks connected to the asterisk server. All incoming DIDs to KX-TDA200 via Asterisk server worked fine. I tested this too using Panasonic KX-NS500 and the result was the same.

For your solution, assuming my interpretation is right, i would suggest you connect your main SIP Trunk to Asterisk and IP trunk the two. I suppose the setup does not vary much. I will interested in knowing your results.

Good Day Guys

Have managed to solve all inbound calls to the Asterisk PBX Via Panasonic NS1000 but my challenge now is that for Outbound calls via NS 1000 I get no audio from the Asterisk PBX.But if I configure that same sip extension which I am using for asterisk on a Soft client the audio is there I don't what might be blocking on the Panasonic side if I configure that extension inside the Asterisk PBX.

Later on I will share details how I have managed to fix all inbound calls to the Asterisk PBX.

RE: PANASONIC NS 1000 trunk-to-trunk calls

If you are not natting audio ports on ns is 12000 to 12511. If you havr a large dsp card that doubles

If the panasonic requested a port say 12001 and the asterisks trys to send it back on a different one, it will not allow it in

RE: PANASONIC NS 1000 trunk-to-trunk calls

@obtsystems well I have managed to fix it it was something to do with codecs on the Asterisk side so I did make some changes and everything started working i.e allow=alaw
allow=ulaw
disallow=all

Those are the changes I did in asterisk and everything worked Just a point I need to share with everyone Panasonic restricts Trunk to trunk calls but they is a work around I did and it worked

1.You create a virtual extension (portable station) and set call forward all to XYZ (trunk group access for Asterisk trunk) + DDI number
2.Remember to set DDI in NS1000 to extension number of virtual extension.
3.Also ensure the NS1000 allows call transfer and call forward to CO for relevant COS

After that I had to create a SIP extension just only for outbound in Asterisk and now things are working fine.

Did you not try the gateway card We have it working with other systems
