I am running the free 3CX PBX instance and only allowed one SIP trunk. Anyone knows if it is possible and how to configure this trunk for both inbound and outbound traffic - same provider? Thanks
Hi,Thanks for the reply. I went ahead and following the linked workflow to configure my trunk for both inbound and outbound. Now i am able to get the outbound to dial out but then quit immediately. On the app it will state "Dialing" then in a couple of seconds change to "server internal error". Call logs will indicate "Not Answered" Any idea how to resolve this?View attachment 71 View attachment 72 View attachment 73
Hi @limdizzoThanks for your response. Usually Endstream authenticates me by my IP address (traffic coming from my IP). I am successfully terminating traffic with them from a different IP for a different service and all i need to do on my end is point my server to their terminating IP.
As with using other providers, there is a huge cost to switching/porting. Explored some of the listed providers and they are very expensive. I have used Endstream for years and they are good.
Thank you very much for your responseHi @limdizzo
Since this is a non supported VoIP provider we don't know how do they want to receive the INVITES from the PBX.
If you check the outbound parameters in the trunk there are many SIP fields that must be set according the provider needs, so please try to contact them directly in order they can bring you the details on every field.
Have a great day!
