Modify caller id on incoming calls analog gateways


Is it possible to modify CallerID of incoming calls on GXW42xx and HT818 gateways? We have problem with analog phones not supporting + sign in callerid. If caller ID is E.164 formatted, analog phone does not show it correct or at all. So, we would like to change + into 00, for example.


No as far i know. You must ask provider.


thanks for prompt reply. I thought so, but I was hoping there was some workaround :slight_smile:
