Grandstream gateway GXW4108 is not working with 3cx server verison 15 or above

[irfan]

Gateway is registered with 3cx server. We can route incoming calls to any extension however we cannot make any outgoing calls.
Our outbound rule is ok
3cx server is not blocking the gateway
with exisiting gateway configurations there is no problem with 3cx verison 14. This problem only occurs in version 15 or above.
We have tried to factory reset gateway
We have tried with freshly installed 3cx server v15 and v155
We have tried to register gateway to 3cx both as SIP trunk and gateway but non worked
and suggestions?

What error, in the 3CX Activity Log, are you getting when attempting an outgoing call? Post a log if unsure about what it is telling you.

Since Grandsteam is not "officially" supported, have you tried for help on the GS forum? As I understand it, they are supplying the 3CX templates for their products.

Using Dinstar gateways is much easier and straightforward. There is a documentation on Dinstar's webpage how to configure gateway for use with 3CX.

Dear sip.bg,
thank you for your suggestion however we do have the mentioned hardware in our hand and we are trying to find a solution to make it work as generic device. We are not after finding a new gateway which works with v15

Dear leejor,
please see our activity log (verbose)
(on the extension screen (phone screen) I see "404 not found")
I have also attached few screen shots

Hello @irfan

Sorry i had to delete your attachments but sensitive info was displayed.

From what i saw from the provided screenshots though your outbound rule is configured wrongly.
When all fields are empty there is nothing for the PBX to match as outbound.
You should specify either group of extensions or prefix or number length so the PBX has something to match.

It sounds as if you need a read through this. https://www.3cx.com/blog/voip-howto/outbound-rules-a-complete-example/ There are several other posts, and examples, on the 3CX site regarding outbound rules as well, if you do a search.

Hi Irfan,
I do have the same Gateway and I could not get it to work. Do you mind to share how is the settings ? I have not have success in register the gateway into 3CX.

 

[irfan]

to register your gateway to 3cx v15 make sure that on your gateway you have below settings are done (still I cannot make calls though)

accounts -> sip settings -> SIP Server: xxx(your 3cx ip)
Outbound Proxy: xxx(your 3cx ip)
Use DNS SRV: No
NAT Traversal (STUN): yes
accounts -> call settings -> User ID is phone number: yes
accounts -> user account -> user account 1:username: XX(same as 3cx) pass(same as 3cx)
user account 2:username: XX(same as 3cx) pass(same as 3cx)
user account 3:username: XX(same as 3cx) pass(same as 3cx)
user account 4:username: XX(same as 3cx) pass(same as 3cx)
user account 5:username: XX(same as 3cx) pass(same as 3cx)
user account 6:username: XX(same as 3cx) pass(same as 3cx)
user account 7:username: XX(same as 3cx) pass(same as 3cx)
user account 8:username: XX(same as 3cx) pass(same as 3cx)
channel settings -> user id: ch1-8:XXXX++; (where xxx is you 3cx main trunk no)
network -> basic settings -> PPPoE account password: xxx (same with you sip gateway password)
network -> basic settings -> ip address: xxx (same with you sip gateway Authentication ID)


from the 3cx server side add sip trunk generic gateway
