    I can't easily do reinvites (in this country port 5060 is blocked so I have
    to use a cumbersome proxy arrangement) and I haven't experienced problems
    with CID, but the one thing about Gafachi that bugs me is the inability to
    send touch tones. Does that work with Teliax?

  2. That doesn't sound like fun. I guess any port in a storm...
    Yes, that is another problem with Gafachi. It is pretty common
    though. I recall I had the same problem with broadvoice too. Gafachi
    and broadvoice need "dtmfmode=inband" to make touch-tones work.
    Eg. inband touch tones sent as actual tones down the audio path. I'm
    not sure why they don't provide sip or rtp command mappings for the
    touch tones, but they don't.

    Teliax runs fine with my default setting of "dtmfmode=RFC2833". I've
    tested it with various auto-attendants and keypresses to navigate
    remote voice mail systems seem to work just fine. The one thing that
    does disturb me about Teliax is that when I plot the ping times to
    their machine it is very, very noisy with some of the pings 4x as long
    as the average. That makes me think they are a much smaller outfit
    and might easily get overloaded.

    This has not been my experience. I was using my Gafachi account last
    week for some CallerID experimentation and had no problem setting the

  4. Interesting! I wonder what I'm doing differently that it objects to.
    How are you setting the caller ID? Are you setting it to a 10-digit
    number or an 11-digit "1+" number?

    This is what I'm doing:


    exten => _1NXXXXXXXXX/6001,1,SetCallerID(WOLFGANG RUPPRECHT <3602267904>,a)
    exten => _1NXXXXXXXXX,5,Dial(sip/${EXTEN}@gafachi-out)



    Now that I look at it, I wonder if the "fromuser" is interfering with

    Here's what I do - caller ID seems to be sent properly:

    exten => _1NXXNXXXXXX,1,SetCallerID(321-654-0987)
    exten => _1NXXNXXXXXX,2,Dial,SIP/${EXTEN}@gafachi

  6. Ok, I see how to get callerid to work with them. The trick was indeed
    to remove the "fromuser" in sip.conf. That caused the authentication
    to fail. To get that to work again one one needed to use the phony
    hostname and their proxy would gleam
    the account number from the hostname. Weird, but clever! Thanks for
    the info that it was now doable.

    One down, one to go. Getting reinvite working is important to cutting
    my local proxy out of the audio path. While the machine sitting on my
    desk makes is a reasonable enough sip-engine, moving the RTP packets
    themselves doesn't work out that well, especially when I'm recompiling
    the world.
