Yeah, technical support is not great.
When you say including the router, do you mean any router, like DIR-1210/DSBNA AC1200 Wi-Fi Router | D-Link (dlink.com) ?
Or some ip pbx thing like, Uc200-30 Asterisk Mini Ip Pbx Support 30 Concurrent Calls And 120 Users With Fxo Fxs Port - Voip Products - AliExpress
What would be a better fit?
I already have an IP phone ( [Grandstream GRP2601P IP Phone]) to verify the sip line.
Also, the installation team has shared this list of pre-requisites,
Mandatory requirements:
- PBX should be able to send the traffic in E.164 format in To, from, and request URI
- Customer gateway should support SIP protocol
- Customer Voice Gateway Supports GE Electrical interface for connecting to JIO L2
switch - Gateway should support configuration of IP (given by JIO) for WAN SIP link
- PBX should be able to support PRACK (Provisional Acknowledgement)
- PBX should support OPTION’s messages
- PBX Should be able to support RFC2833 DTMF method, payload can vary
- PBX Should support Timer
- PBX should have G.711A/U codec support
- Customer is responsible for configuration, provisioning of Voice Gateway with
VLANs, Host IP, Gateway IP, Subnet, DID, Pilot range given by JIO - Customer is expected to test out all the options (incoming , outgoing, Different
Circle calling across operators) in a weeks’ time from Delivery of SIP services by JIO
Nice to have - PBX supporting Update message call flow
- PBX sending G.711A CODEC only
- PBX Set for refresh update after 1800 sec.
- PBX supporting RTCP
- PBX sending Q.850 signaling in BYE message / error response
- PBX supporting Media attributes for HOLD/RESUME conditions.
- PBX should not sending
- PBX sending 18X message with SDP ( Ring back from PBX)
- PBX supporting delayed offer method ( INVITE without SDP )
While I am thinking that if I can get a RJ45 then I should be able to setup Asterisk.
