Dear Experts, I am having this problem with E&M VoIP. We are using an E&M PABX operating with 4 wire and using immediate signalling. The network are connected via 2 Mbps Leased Line. I can make voice calls from my site to remote site, however when i asked someone from the remote site to call the other way around he get busy tones all the time eventough the extension were actually not bust at that time.
The strange thing is that the remote site can make voice call to my site only to 2 extension (300 and 400), but when they dial another extension ex: 363, or 369 they get busy tones all the time. the dial-peer configuration on the remote router are like this dial-peer voice 1 pots destination-pattern +... port 1/0/0 dial-peer voice 1 pots destination-pattern +... port 1/0/1 dial-peer voice 3 voip destination-pattern +3.. session target ipv4:172.23.1.34(ip address of router's serial interface at my site). dial-peer voice 4 voip destination-pattern +4.. session target ipv4:172.23.1.34 (ip address of router's serial interface at my site). Is it the wiring arrangement problem? i already set up the wiring arrangement based on a reference i got from CCO. Is it a timeouts parameter problem? or Is it the E&M PABX problem? Like always, the PABX technician feel that he has done everything correctly. I am also confident that i have done the configuration correctly. Anyone has similar experience? Any idea would be greaty appreciated. Thanks in advance.
