ERROR

I have two Grandstream budge tone-100 phones (same number ) connected to my router set up with default settings and plus network settings.
They work fine and can dial each other also . However i get calls usually in a evening may be other times also, they last for 10 bursts of ringing then clear (one phone only) while ringing 'error' is displayed.  By swapping phones and using a spare i am pretty sure its not the instrument. This leaves set up and provider problems in my mind but can any one help this is difficult.

Re: ERROR

Does it work ok if you only have 1 phone connected to the router ?

Re: ERROR

I will try that out and get back to you but will have to give it a few days to confirm.

Re: ERROR

If it works ok with only one phone connected then you probably need to modify the phone configuration so that each phone uses a different local port. According to the manual ( page 33 & 34 ? ) you can either specify a local port ( default is 5060 ) or set it to use a random port.

It certainly looks like you fixed this straight away. I looked at the handbook and went straight for random port and so far no recurrence, so very pleased thank you very much for your assistance.

Re: ERROR

You're welcome, having multiple voip phones connected to the same router can often be problematic  to setup.

Re: ERROR

I get that sometimes and I've logged a couple of sessions using a protocol analyser. It is just hackers speculatively sending SIP  packets to IP addresses looking for vulnerable VOIP systems.
