I’ve been Googling for a few days now but can’t find an answer to this.
I have Asterisk setup so if i dial 7 before a number then the call will go out my Sipgate line (as opposed to the PSTN).
What i would rather have is, if i push line 2 on my Aastra 480i phone the phone will add the 7 prefix for me.
I thought this would be easy but i haven’t found any info on it.
Slightly off-topic, but does anyone know how to do this on an Aastra phone?
