Hi,
I am having some very odd issues with a very basic phone setup and was hoping someone could maybe help shed some light on things.
The setup is just a 4 phone build, very basic, one ring group that rings all 4 phones when calls come inbound (other setup as well, but nothing major). The customer is switching their internet provider to a new provider. If the system is on the old provider, which is a slow DSL connection and a basic dlink router they have, everything works without issue. As soon as I switch the provider to a new business cable connection (using modem in bridge mode and same router that works on other provider) calls cannot be answered. I also tried switching the modem out of bridge mode and letting it do the routing and still the same. If I call in, the exts all ring, if I answer from any of the phones you cannot hear anything and all the phones continue to ring, including the one that I just answered from. It will not call between phones or anything.
I was thinking maybe some kind of NAT issue, but the same router setup the same way is being used. As soon as I switch things back to the old provider, everything immediately starts working correctly again. Even ifI leave one of the phones on the old provider and put the other 3 on the new provider, the one phones works correctly and the other 3 do not.
I do not understand how it could be anything but an issue with the provider, but before going to them and having them investigate further I wanted to see if anyone else has seen/resolved similar issue before.
Oh, also, the phones are Grandstream GXP2130 phones.
Thanks
