Hi,
here is my config:
cucm 8.5
cisco router as gateway to PSTN
bunch of cisco and dlink ip phones and CIPC
everything works properly and all SIP and SCCP phones can connect to each other and dial off-net numbers by dialing 9 as prefix.
I installed SIP soft-phone like x-lite on windows and csip on android and they can communicate with each other and the rest of ip phones.
The problem is when I dial off-net number with SIP soft phone(x-lite or csip), call disconnects shortly.
Any help will be appreciated.
