[asterisk-users] FXO -> GSM Gateway Problem

[Tech]

Hi,

 

I have a problem where calling "out" of asterisk when the call is answered
dahdi hangs up immediately.

For example: Sip Client A calls external number. Route: SIP -> FXO -> GSM
Gateway ->External Landline.

However when that external landline answers the call dahdi hangs up
immediately .

 

Going the other way is fine (External Landline -> GSM Gateway -> FXO ->
SIP).

 

I've tried multiple different internet searches and can't seem to find any
information on this problem.

 

Below are my config files.

 

Sip.conf

[office-phone](!)  

type=friend         

context=sipofficephone   

host=dynamic        

nat=yes             

#secret=xxxx 

dtmfmode=auto       

disallow=all        

;allow=ulaw          

allow=alaw          

allow=GSM

 

[lewisphone](office-phone);lewis mobile

secret=xxxx

 

Chan_dahdi.conf

[channels]

signalling=fxs_ks 

context=pstnincomming

group=0

channel => 1

 

 

Extensions.conf

[sipofficephone]

exten => _X.,1,Verbose(2,Call from VoIP network to ${EXTEN})

        same => n,Dial(DAHDI/1/${EXTEN})

        same => n,Hangup()

 

[pstnincomming]Diamon

exten => s,1,Answer()

        same => n,Dial(SIP/lewisphone)

        same => n,Hangup()

 

 

Asterisk CLI Output (Verbose 3)

My comments bold.

 

  == Using SIP RTP CoS mark 5

    -- Executing [xxxx at sipofficephone:1] Verbose("SIP/lewisphone-0000000a",
"2,Call from VoIP network to xxxx") in new stack

  == Call from VoIP network to xxxx

    -- Executing [xxxx at sipofficephone:2] Dial("SIP/lewisphone-0000000a",
"DAHDI/1/xxxx") in new stack

    -- Called DAHDI/1/xxxx

    -- DAHDI/1-1 answered SIP/lewisphone-0000000a GSM Gateway Answering Call
then Sending it out.

    -- Hanging up on 'DAHDI/1-1' Dest answering call to which DAHDI hangs up

    -- Hungup 'DAHDI/1-1'

  == Spawn extension (sipofficephone, xxxx, 2) exited non-zero on
'SIP/lewisphone-0000000a'

 

 

 

Best Regards
