The stations do not like CLIP "+..." and accordingly the number on the display is not visible.
In the problem was solved by changing OXO label IsdnTransp.
What should be done in OXE?

Did you tried to remove first digit in callback translation? (DEF number of digits to be removed-->1)

No fails. The process does not reach Ext. Callback Translation.

Remove + in your GSM gateway configuration. It may be the simplest way.
I didn't faced such configuration so I don't know if this is possible on ISDN on OXE. Usually + is in SIP canonical config.

Gateway TelecomFM is limited to the configuration.
A similar problem was solved in OmniPCX Office.
