[asterisk-users] How to append "#" to the number before sending to Zap

[Terry Gilsenan]

Hi,

I am using freepbx 2.8 and I am wanting to connect a TDM410P to an
Inmarsat M4 terminal.

All is working, except that I dont seem to have a way to append a "#" to
every number that gets sent to the ZAP channel.

I dont want the "#" appended to any dialling of other extensions, just
when outward call routing sends the call to the ZAP trunk.

Note; this is appended to the end of the dial string, not as a prefix.

Thanks for anyone that can point me in the right direction.

Regards,
T
