Dear all, Please find bellow instruction we need to connect to our coorporate VoIP system ? Could you please assist me in proving me answer requested by our technical team ? Thanks. a. PBX should forward and receive calls via IP trunk(s) - using sip protocol. b. OUR Voice Gateway is running of g729r8 codec bytes 60. What is the codec configured on the local PBX? c. Voice gateway will be sending the complete number 25702xxxx (country code + agency code + extension number) when forwarding calls to the PBX. d. When PBX forwards calls via IP trunks (using protocol), it should send the complete number to the Voice Gateway (gateway IP to be confirmed by us), for example with on-net calls for no cost: +264026111 (Country Code + Agency Code + Extension Number) and if making an off-net (outside): +00 264 61 204 6111 (International access code + country code + area/network code + local number).
