Hi everyone! Yesterday I’ve connected landline number. I have my own router (I don’t use T-Mobile modem) and I installed IP Phone (Yealink T31G) using settings provided by T-Mobile.
And when I started to test it I found very strange behaviour - I cannot call any numbers in +31XXXXXXXXX format. It fails immediately or after some time-out. But everything works fine if I call in local format - 0XXXXXXXXX. If I call from my mobile phone to landline - +31XXXXXXXXX number is displayed, so I would expect it’s supported, but when I click redial - it adds some IP address (with “@” symbol) at the end and fails. The same happens if I create a record in the phone book with the same number (+31) and try to call from there.
As a result now I need to create contacts in the phone with 2 different variants of the same number:
- 0XXXXXXXXX - to be able to call that contact from IP Phone
- +31XXXXXXXXX - to be able to detect a contact for incoming calls

@Romtje, welcome to the Community! 🙋♂️
I honestly have no clue as to what might be the root cause here, but I’ll gladly ask our local expert.
@yalerta Do you perhaps have an idea? Thanks in advance!
Try 0031 instead of +31?
Just looked in to this manual but I could not find any setting wich should look like something as “Call Prefix”
A call prefix makes it possible to dial numbers in your local area so you don't have to dial those area nummers.
On page 86 of the manual I found “clearing local settings”. Maybe thats an option?
I have no knowledge if this issue is due to the connection to the Tmobile Sip/Voip connection.
Thanks everyone for your answers!
@Romtje, I'm really glad to see that it's working again after the tips! 😁 If you have any other questions, please let us know. For now: enjoy your weekend.
