Hi,
I'm having trouble with dialing out on analog lines. Asterisk can't seem to
detect "answers".
I have two zap groups.
Group 1 is connected to an external analog PSTN provider. This group seems to
work fine, especially with "answeronpolarityswitch".
Group 2 is a group of "GSM gateways", ie. devices that host SIM cards so that
you can dial from any PBX extension to another phone via a GSM SIM card
(supposedly, calls to cellular phones are cheaper this way). These devices act
just like any other analog line.
Every time I dial out through these analog GSM gateways the call gets through
just fine. However, if the call lasts more than the timeout set on the Dial()
application then it gets cut off. Also, if the call terminates, the CDR always
records "NO ANSWER" even if it actually has been answered. During the call
(answered and active), asterisk -rx "show channels" shows that the calls made
out through group 2 are in "Ring state".
Any ideas on how I can detect "answers" on analog GSM gateways?
example CDR:
"","7070","600000000","outbound","""TEST""
<7070>","IAX2/mgmbox-1278","Zap/6-1","Dial","ZAP/g2/600000000|300|TWf","2009-12-29
08:30:00",,"2009-12-29 08:30:10",10,0,"NO
ANSWER","DOCUMENTATION","1262075400.294",""
