Hi,
we have a SnomOne Yellow over a patton gateway.
On making an outdial, our telephones did not play a normal ringtone.
The patton gateway is signalling correctly the "RINGING".
On calling a mobile phone, no ring tone is played, on calling a national number there are three tones, then a little pause.
On calling another subscriber, no tone is played.
Some ideas?
Best regards
Chris
