Incoming calls all on 1 SIP trunk

[SAToronto]

Can anyone tell me if this is my pbx issue or SIP providers

I have 19 Sip trunks on my 500 v9.3
It appears that all incoming calls are being picked up by 1 trunk only
As soon as the channels fill up on trunk #1 all callers get a busy signal even though I still have all the other trunks empty and at that point only 10 trunk channel licenses in use

Thanks to all!

It can be either or
Check your incoming call route and make sure that the target can handle more than 1 call at a time or try a second number on the SIP trunk with a different target and see if that works while the other one is busy.

The trunks don't "pick up the calls", the provider merely presents the call in on a number, if 10 calls all come in on that 1 number then they will all appear be on 1 trunk. I assume you have 19 different trunks from different providers or have you misunderstood how SIP works and created a trunk for every DDI from the 1 provider?

I have 350 DIDs from my SIP Vendor
I have 19 trunks configured, however 9 are configured for failover and connect to the vendors SBC on the other side of the country
So in theory...10 trunks with 10 channels each means I should be able to have 100 calls either direction at the same time
However ALL the incoming calls are via the 1st trunk and NO others!!

All calls go through AA and as we speak I have 8 incoming and 27 outgoing

Yes, how it is is how it should and will work. Having 10 trunks with 10 calls would be no more advantageous than 1 trunk with 100 calls anyway, it's all data coming in the same LAN port over the same connection at the end of the day....However having 10 SIP trunk licences will only ever allow 10 calls, not 100 over 10 trunks, I have you have misunderstood how it works...

 

[amriddle01]

Or do you have 100 licences? If so you need to up the fist trunk to 100 calls

I do have the licenses. Is this by design in the 500? that all incoming will always come in on the 1st trunk?

You can't configure 10 trunks with the same number assigned to them. All the IP Office gets from the provider is a number@IPaddress, it checks if that's valid and show it as a call against the trunk that has that matching data. The provider will not be presenting on 10 different trunks either they just send the number dialled to the IP address they have for you.

It's a bit like creating 10 huntgroups with the same extn and wondering why it only ever rings in on 1 of them.

Also I don't see what advantage you think it would have were it possible to do this?

Jumping in with basics here,
in the lines=>
Sip line XX(line #) =>
Sip URI =>
and look for "max calls per channel" this should control the number of trunks you are giving that line(this is the number if sip Trunks purchased from the provider)

So it looks like one line but has multiple SIP trunks in it. Then you assign the Incomming call route with the DID and then in the extn=> Sip tab you enter the number of the caller ID you want to send out. Think of it as a virtual t-1, 1 actual circuit but many trunks.

I reread the original question and i think you have the ideal but a misunderstood config. I hope this helps, I think this is the direction your looking for, the symptoms seem to point to this if of one trunk used, then all go busy is the result of the "max channels being set to "1" not 19.
let us know if im in the right area or way off.

19 SIP trunks is ofcourse total bullocks.
Get a decent provider who can assign all those numbers to one trunk.
A second trunk to a second SBC and you should be done.


BAZINGA!

I'm not insane, my mother had me tested!

1 Trunk should have 19 channels.

Not 19 trunks with one channel

My mistake, I meant Channels in trunks. I was reading about so many trunks I started talking in that direction..
