Calls to/from external lines hangs up quickly in Axon Posted June 13, 2009 Hello everybody. My target is to implement a low-cost pbx system using USB phones for extensions and (up to 4) voice modems to connect PSTN lines. I just installed Axon v.2.04 trial on a PC having a voice modem. Installation was successful, the modem was recognized as an external line (in the "Land Line" list) The default setup with Internal "Carousel FXO Gateway" seems to be ok. The problem that i'm facing is that the connection with the external line hangs up immediately after it has been established. When i dial an external number from an extension i can hear the modem dialing the number and hanging up immediately. When i receive a call from the landline, the extension phone rings a few times, the modem answers the call and than hangs up. Here is the test platform i used: The Axon machine: - AMD Athlon, 1.5 Ghz, 256 MB of RAM, Win XP SP2 - Axon v.2.04 trial (10 more days to play with all features) - Intel® 536EP Modem (manufacturer: Wayjet) I tested the modem with Voice Modem Tester from http://www.orangeview.net/voicemodem/ Another machine in the same LAN: - 3CX VoIP phone software, used as extension. Below are portions of Axon log during the testing of an incoming and outgoing call respectively: 12:11:50 Incoming Call from: unknown on Line: Intel® 536EP Modem 12:11:50 Dialing number: Carousel 12:11:50 Initiated sip call to: Carousel 12:11:50 Call sip:9Carousel@localhost -> 701 12:11:50 Call answered 12:11:53 Joining Lines... 12:11:54 Call from Line to Carousel bridged successfully 12:11:54 Call has disconnected 12:11:54 Call sip:9Carousel@localhost -> 701 disconnected 13:25:42 Call 101 -> sip:80722296500@192.168.227.151:5060 13:25:42 Incoming Call from: Carousel on Line: Carousel 13:25:42 Dialing number: 0722296500 13:25:42 Incoming SIP call 13:25:47 Answering call... 13:25:47 Call 101 -> sip:80722296500@192.168.227.151:5060 answered 13:25:47 Joining Lines... 13:25:47 Call from Line 0722296500 to bridged successfully 13:25:47 Call has disconnected 13:25:47 Call 101 -> sip:80722296500@192.168.227.151:5060 disconnected Considering that nowadays everybody is trying to cut costs by all means, such a solution could be interesting. So, i would appreciate any information that could help me in my test project. P.S. By the way, i succeed to do incoming/outgoing calls using Uplink as external line, instead of Carousel with modem. It all works fine ! And it would be pitty not being able o make a pbx that can talk with local numbers on PSTN lines, and with long-distance through Skype.

Hello everybody.
My target is to implement a low-cost pbx system using USB phones for extensions and (up to 4) voice modems to connect PSTN lines.
I just installed Axon v.2.04 trial on a PC having a voice modem.
Installation was successful, the modem was recognized as an external line (in the "Land Line" list)
The default setup with Internal "Carousel FXO Gateway" seems to be ok.
The problem that i'm facing is that the connection with the external line hangs up immediately after it has been established.
When i dial an external number from an extension i can hear the modem dialing the number and hanging up immediately.
When i receive a call from the landline, the extension phone rings a few times, the modem answers the call and than hangs up.
Here is the test platform i used:
The Axon machine:
- AMD Athlon, 1.5 Ghz, 256 MB of RAM, Win XP SP2
- Axon v.2.04 trial (10 more days to play with all features)
- Intel® 536EP Modem (manufacturer: Wayjet)
I tested the modem with Voice Modem Tester from http://www.orangeview.net/voicemodem/
Another machine in the same LAN:
- 3CX VoIP phone software, used as extension.
Below are portions of Axon log during the testing of an incoming and outgoing call respectively:
12:11:50 Incoming Call from: unknown on Line: Intel® 536EP Modem
