G400E - hanging up?

Hi!

I've got a problem with my G400E card. There are 2 M20 modules installed. Everything works like a charm when one card is used, but the problem begins when I want to use both SIM cards.

I'm able to call from my Asterisk from both cards all the time. But I cannot answer a second call when first "line" is used.

Usually I see that Asterisk tries to communicate with second SIP account and the respond is: BUSY HERE. Caller hear busy tone. That's probably, because both SIP accounts are configured on the same IP Phone on the same SIP port (I will try to do something with that).

The real problem starts after a while - one hour or less. When first card is in use and someone try to call a second "line" on the same time, CLI does not show anything about that. A second caller hears waiting tone (standard - not changed by Asterisk). So it looks that G400E is not aswering at all. If second caller hangs up, then first call is also disconnected.

How can I solve this problem?


Best regards,

Now I call to a second number:

2:<<< 0 ATA -- +CSQN: 13, 7 , 12
2:<<< 0 ATA -- +CSQN: 16, 7 , 12

2:<<< 0 ATA -- +CSQN: 15, 7 , 12

On the second phone I hear standard waiting tone (not aswered by Asterisk). I disconnect a second (not first) connection and that happens:

2:<<< 0 ATA -- +CSQN: 14, 7 , 12
2:<<< 0 ATA -- NO CARRIER , 10

What's wrong?

Hi,
Please show me your OS and software version.(OS,asterisk,dahdi,chan-extra)

CentOS - 6.4 (final)
Kernel - 2.6.32-358.6.2.el6.i686
Asterisk - 1.8.18.1
Dahdi - 2.6.2
Chan_extra - 2.0.7


Update 1:

I've forgotten to mention that both SIM cards have the same phone number.

For now I've noticed that "call waiting" feature is switched on somewhere. But I don't have idea where to look for it. I have already changed settings in chan_extra.conf and chan_dahdi.conf.

I've made some more research:
When the first call is in progress and someone else try to call me, than I hear a signal about second incoming call. On the same time, second caller hear a standard (not asterisk) waiting tone.
Now, the worst thing: if second caller hungs up, than first connection is also disconected (as showed in post #2).
If the first caller hungs up, while a second one tries to reach me, than he is connected with me (see below).


CLI output:

-- Accepting call from '94xxxxxx' to 's' on channel 1, span 2
-- Executing [s@from-gsm-200:1] Answer("EXTRA/3-1", "") in new stack
-- Executing [s@from-gsm-200:2] Dial("EXTRA/3-1", "SIP/200") in new stack
== Using SIP RTP CoS mark 5

In the meantime I call from a second phone.

-- Called SIP/200
-- SIP/200-00000015 is ringing

I have decided to stop first call:

-- Channel 1, span 2 got hangup, cause 16
== Spawn extension (from-gsm-200, s, 2) exited non-zero on 'EXTRA/3-1'
-- Hungup 'EXTRA/3-1'

Now asterisk reacts on the second call:

-- Accepting call from '40xxxxxx' to 's' on channel 1, span 2
-- Executing [s@from-gsm-200:1] Answer("EXTRA/3-1", "") in new stack
-- Executing [s@from-gsm-200:2] Dial("EXTRA/3-1", "SIP/200") in new stack
== Using SIP RTP CoS mark 5
-- Called SIP/200
-- SIP/200-00000016 is ringing
-- Channel 1, span 2 got hangup, cause 16
== Spawn extension (from-gsm-200, s, 2) exited non-zero on 'EXTRA/3-1'
-- Hungup 'EXTRA/3-1'


Update 2:

I've tried to send AT commands: gsm send at 1 "AT+CCWA=0", but it doesn't helped.

Hi,
Now the driver chan-extra is not support the "call waiting" feature, you should turn off this feature!

I would like to, but how can I do that? Maybe that's made by operator... I'll check that.
