The caller from outside does not get any tone if i forward my ip phone 7940 to my mobile.
All calls from outisde are coming into the PBX. PBX and ITS (Cisco 1760) are connected with a VIC-2BRI-NT/TE over Qsig.
The PBX calls my mobile via public telephony network
What version of IOS are you running?
Did you try adding progress_ind alert enable 8 under your pots dial peer that goes OUT to the PBX to call your mobile.
IOS is 12.2(15)ZJ1. Yes. I tried, but it does not help.
you may need ansp (answer supervision) set to yes in your route data block. that would give ring back during call setup
