We're in teh process of setting up a Grandstream UCM6102 PABX in our offices. It currnetly has two analogue trunks (both over ATA's from different providers) that we're phasing out and replacing with all our lines coming over a 2Talk SIP trunk.
While testing today from a vodafone mobile, we noticed that the incoming line rings about five times before the extension starts ringing. Can we improve this, or is that normal?
