Network settings and VOIP phone issues
My problem relates to a VOIP phone adapter not staying connected to the router.
My router is Cisco Valet M10 on DD-WRT v24-sp2 and the phone adapter is Grandstream HT502.
This setup has been used for the main home phone for quite some time. But starting in May this year, the phone adapter keeps losing connection to the router.
Of course I didn't change any router or phone adapter settings when this first started happening, and I've been too buy to deal with this. Good thing I don't get too many calls on my home phone, but since the whole point of having a home phone line is to actually have it and have it working, I would like to fix this.
I am with voip.ms and I've spoken with their tech rep, and I've been told to change the port from 5060 to 5080 and stuff, but none of that helps.
I have quite a few devices at home. My main computer and the said phone adapter are two devices connected to the router directly. There are two other computers, three tablets and one cell phone and a wifi printer that regularly connect wirelessly to this router. Everything else works fine, but only the phone adapter loses connection. Sometimes if I reset the phone adapter, or physically disconnect and reconnect the adapter to the router it would work for a short time before losing connection again.
Can someone help me out with this?
I wish I could give more information but I don't know much about the networking, and I couldn't even tell you where to start. If you tell me what I need to tell you to help you help me, I can probably find out and tell you.
I've already reset and reconnected all the network components (the modem, router and phone adapter) with not success.
This is a big project for me. I am open to getting a new router or phone adapter, if it would solve the problem, but I'd like to try solving it without spending money that I don't really need to.
