How would I go about dynamically changing the dail tone given by my Sipura 2000 ATA? I know it’s possible to set a variable (ALERT_INFO) to control the ring tone generated by the Sipura. Is there something similar for dial tone?
I want to warn the user (me) when calls are being routed straight to voicemail, something I activate/deactivate by dialing a certain extension.
Hmm…But Asterisk does, in a manner, change the dial tone by alerting the Sipura that there is a new voicemail. When I pick up the phone, the dial tone beeps about 6 times to tell me there is voicemail. If I listen to the voicemail, next time I pick up the phone, dial tone is normal.
I don’t think that’s true. Not with SIP, anyway - although it’s undoubtedly true with FXS cards. Asterisk doesn’t provide the dialtone heard in an ATA or SIP phone - it has to be the phone that creates it.
