Thanks for the replies! I think I had too many questions

| Is the country for 0036 in the list of possible terminations for 0871? |
Of course. If it weren't I couldn't make a forward to it.

404 means the user could not be found or is offline. Is he able to make outbound calls with his grandstream ?
If his outbound is working 100% and you are still having problems, please send me a private message with the usernames and the corresponding 0844 numbers and i'll have a look, but please double check again to make sure the outbound is working before you send me a private message. |
He can use the outbound service for calling wired landlines. So both he and I can make outbound calls with our grandstream. I checked his original 0844 number again, but it did not work

See the exception in the next paragraph!

| Can you call his 0844 from a landline? |
Both of us can be called on the 0844 number from a landline, but only the additionally requested 0844 (and 0870) numbers worked so far from a landline. The original 0844 numbers (we got automatically with registration) couldn't be called from landline nor peer-to-peer (or SIP-to-SIP), as it was said earlier in this thread. So I think there cannot be firewall problems, because we can not only call, but can be called.
It is said the latest beta firmware can log to a syslog server. I tought if nothing helps, I upgrade my Grandstream to that, but this is the last thing I want to do, because beta firmwares just have the risk of not being stable or cannot be downgraded.
