SIP access

You can now telephone without using an access number with telmy using our SIP access. Enter the required call number directly using a softphone or using your landline telephone with an upstream SIP adapter.

The contacts in your telephone book can also be dialed from here using the short code numbers.


  • First simply dial the 0 and you will enter the service as normal.
  • First simply dial the 1 and your first telephone book entry will be called.
  • You can simply call the number that you want to reach, e.g. 030 555 555 55

Telephone using the SIP access and transmit your own call number. Before using this service, you must verify your call number in your customer centre once only.


If you have any problems, please contact our customer centre at
