[Asterisk-Users] Incoming voice "disappears"

[Tony Davidson]

Apologies if this has already been posted to the list.  I sent it about 
an hour ago and it hasn't shown up yet.  I've changed the format to 
plain text in case that was the issue.

I'm having a major issue whereby voice is going out fine but none is 
coming in.  If I ring someone I will hear them answer and then nothing.  
They still can hear me.

Looked at the logs and with my limited experience can't see anything 
strange.  This is the info on the screen:

    -- Executing SetVar("SIP/203-b69b", "DIAL_TRUNK=2") in new stack
    -- Executing AGI("SIP/203-b69b", "fixlocalprefix") in new stack
    -- Launched AGI Script /var/lib/asterisk/agi-bin/fixlocalprefix
  fixlocalprefix: Removed prefix. New number: 61xxxxxxxxx
    -- AGI Script fixlocalprefix completed, returning 0
    -- Executing Dial("SIP/203-b69b", "IAX2/82146514/61xxxxxxxxx") in 
new stack
    -- Called 82146514/61xxxxxxxxx
    -- Call accepted by 210.80.176.12 (format gsm)
    -- Format for call is gsm
    -- IAX2/82146514/2 is ringing
    -- IAX2/82146514/2 stopped sounds
    -- IAX2/82146514/2 answered SIP/203-b69b
    -- Hungup 'IAX2/82146514/2'

The other strange thing is that if I call my office on the PSTN line 
when the * box their answers and goes to voice mail I can hear 
everything fine.  The info all looks as per the above.  FWIW this is 
also the case (i.e. works fine) if I call another * based PBX and go to 
voice mail (for testing - no one's there either).

I don't believe I've made any changes to the configuration I've been 
running happily for about 2 months.  It's an *@home 0.7 setup with a 
Sipura 3K providing the FXS & FXO ports. I've got a Draytek Vigor 2900VG 
providing routing and QOS.

In my bumbling way I've tried changing the codec to ilbc - no 
difference. Rebooted about 5 times. Removed the trunk and reconfigured. 
Tried different extensions.  All to no avail.
