The cabled internet in our doctors office can be pretty bad. Therefore I want to provide an internet connection with the RUT950 sim router.
The office has a local network (LAN) consisting of 5 computers and a PBX system. The computers are connected to a simple switch. The switch and the PBX system are connected to the internet router (using the LAN ports on the router).
When using the RUT950 sim router there is internet on the network and inbound calls can be placed on the PBX system. However, no outbound calls can be placed with the PBX system.
When using the cabled router (Arris TG3452) there is internet on the network and the PBX system allows for inbound and outbound calls.
The PBX system is provided by the telecom provider Digicel and has 4 SIP lines. The hardware consists of
- - Yeastar S20 (PBX)
- - Unify Switch 8 port UB04 US-8-150W
- - Ubiquiti EdgeRouter ERLite-3
- - Yealink T21P-E2 (PBX phones)
On 20 October 2021 I did a full reset of the RUT950 router and updated the software. It took some fidling but eventually the 4G internet worked. Hereafter, I connected the RUT950 on 26 October 2021 and checked:
- - internet connection on network (YES)
- - inbound calls (YES)
- - outbound calls (NO)
The troubleshoot file is attached through the link below.
Please let me know if any other information is needed.
