[Asterisk-Users] TMD400 FXO <-> Nokia 32 GSM (Hangup Problems)
Hi, I have a TDM400 FXO module connected to a Nokia 32 GSM Terminal ( http://www.nokia.com/nokia/0,,56025,00.html ). Outgoing calls from asterisk to the Nokia work flawlessly. Incoming calls from the Nokia are working fine when asterisk hangs up the call. However, when the far-end hangs up (i.e., the Nokia GSM hangs up the call), asterisk detects the hangup but fails to put the line back onhook and the GSM terminal stays with the line busy until I reload the zaptel/wcfxs modules. I think this is due to some kind of electrical problem and did some voltage measurements by using the debug mode in the wcfxs module. As I understand it, the voltage should be around 48V when the line is onhook. When a call comes in it starts to drop until it reaches 7V, meaning the call is connected. During the call is stays at this value and when the Nokia hangs up it drops the battery for 500ms (this process is called Disconnect Supervision). Asterisk detects this correctly as the Hangup signal and should "open the circuit" so that voltage goes back to 48V indicating the line is onhook and ready for another call. The problem is that the voltage only goes to ~37V instead of 48V and the Nokia terminal still thinks Asterisk has the line offhook. I have included some of these logs. Any help/hints on what causes this problem will be greatly appreciated. I've also looked at the source code of wcfxs.c and despite having a broad idea of how it works, I'm not at all comfortable with messing around with it's low level internals. Hints on any "hacks" to the code that could solve this would be great. Oh, and can anyone tell me what "Debounce" is/does ? Thanks, Leandro ---------- /var/log/messages ------------ -->NOTE: 48V meaning line is onhook and ready for a call Nov 13 19:27:21 raider kernel: Module 2: Installed -- AUTO FXO (FRANCE mode) Nov 13 19:27:21 raider kernel: ProSLIC on module 3, product 0, version 0 Nov 13 19:27:21 raider kernel: Module 3: Not installed Nov 13 19:27:21 raider kernel: Found a Wildcard TDM: Wildcard TDM400P REV H (4 modules) Nov 13 19:27:21 raider kernel: Card 3: Voltage: 48 Debounce 0 Nov 13 19:27:21 raider kernel: 7278595 Polarity reversed (0 -> 1) Nov 13 19:27:22 raider kernel: Card 3: Voltage: 49 Debounce 63 Nov 13 19:27:24 raider last message repeated 6 times Nov 13 19:27:24 raider kernel: Card 3: Voltage: 48 Debounce 63 Nov 13 19:27:25 raider kernel: Card 3: Voltage: 49 Debounce 63 Nov 13 19:27:25 raider kernel: Setting FXS hook state to 0 (00) Nov 13 19:27:25 raider kernel: Setting FXS hook state to 0 (00) Nov 13 19:27:25 raider kernel: Registered tone zone 2 (France) Nov 13 19:27:25 raider kernel: Card 3: Voltage: 49 Debounce 63 Nov 13 19:27:27 raider last message repeated 5 times Nov 13 19:27:28 raider kernel: Card 3: Voltage: 48 Debounce 63 Nov 13 19:27:28 raider kernel: Card 3: Voltage: 48 Debounce 63 ...

Does the Nokia 32 GSM provide you with a hangup tone? (I.E. beep beep beep once it has hung up) 2. You have specified France as the zone, are these the tones that the Nokia unit produces? If you have some audio files from voicemail of the busy signal, you can send them to me and I can create a custom indications.conf entry for you (assuming it is different from all other countries in indications.conf). Let me know. -- Cheers, Matt Riddell _______________________________________________ http://www.sineapps.com/news.php (Daily Asterisk News - html) http://www.sineapps.com/rssfeed.php (Daily Asterisk News - rss)
