SPA 8800 With Immarsat Conection on FXO

Hi We are trying to connect an imarsat phone to the FXO port of the SPA 8800

However I seem to be runing into issues with the DID number the number I have from suplier is +870122122890

When I try and put this number into the Connections  Seetings Tab It keeps telling me I can only have 6 digits

We also are making use of the E1's one to the PSTN who pass 4 digits ad the other to another router via e1

the line Usage is All Call Types

What I dont understand is where theis 6 digit limit is coming from if I leave it blank it indicates I ca have 23 digits


SPA 8800 With Immarsat Conection on FXO

HI Steven,

The DID on FXO trunk is the incoming called number, which typically will be assigned to the main number of that company or the Autoattendant number, that callers can use to reach other extensions.

It is a combination of extension length and the prefix and total length is same as length of main number that is configured on System - Dial Plan page. In your case, looks like the total length of digits configured on main number is 6 digits.
