Hi folks - I’m having a slight issue with my remote SIP phone. I’ve got the correct ports opened up on the peplink and the phone is showing a register status and is connecting to our internal PBX system just fine. I have logs to show this connection to the PBX and all seems to be a-ok. I have also turned off ALG on both the Peplink and my remote Netgear router.
The issue seems to be the INVITE string that gets sent from the remote SIP phone to the peplink - we currently see all the correct packets on the WAN side but when we look for them on the LAN side of the peplink appliance the INVITE string is no where to be found on the LAN side. We are however getting NOTIFY and CANCEL request from the SIP phone on both the WAN and LAN side.
We are using the following:
Hardware Revision - 2
HA mode with three WAN connections - Cox Fiber - ATT Fiber and Cox Cable.
Firmware - 8.0.0 build 2636
Everything else seems to be working great - I hope someone can assist me on this as we need to stay on this version for the OpenVPN capabilities.
