asterisk users - Jun 2005 - Unable to find a path from g729 to gsm

Greetings! to all

Now, with some hard time and help from many genurous people's in the list, I
have come to this point with my TDM20B card & my teliax's IAX2 account.



I hope someone may help me with this issue mentioned below. I have already
selected my codec as gms in my iax.conf as well as in teliax's  "my
account
page" but still i have the same error when I attempt to make a call.



Second, my last digit is not allowed from teliax. that means I need one more
digit from teliax for dialing through them.



Third, I have somewhat poor support from teliax since I have send them 3,4
emails and so far i got no replies.



Please, help me to go ahead from this point

Thanking all of you,

Kumara.

Based on the CLI stuff shown below, it would appear you have sip.conf
entries for your phone defined as g729 and you haven't purchased/installed
that codec. Either purchase it (www.digium.com) or change your phone
definitions to something usable (g711u).

This also sounds like a user configuration error. Without seeing the
appropriate sections of sip.conf, extensions.conf, and iax.conf, its
almost impossible to answer your questions with pure guessing.

As noted above, your issues seem to be asterisk configuration issues 
and teliax cannot be expected to resolve those for you particularily
with no config data, etc, supplied.

If teliax is truly using the gsm codec, then apparently your phone is
configured to use g729 only. Change that to g711u and try again.

The above does say you are sending the appropriate number of digits to
teliax. Why are you thinking that you need to send "one more digit"?
