Hello,

I have the following problem when I send fax to asterisk:

     -- Executing RxFAX("IAX2/1002 at 123.123.12.12:4569/2",
"/var/spool/asterisk/fax/_1125039307.1.tif") in new stack
2005-08-26 06:55:09 NOTICE[30852]: channel.c:1317 ast_read: Dropping
incompatible voice frame on IAX2/1002 at 213.210.63.73:4569/2 of format
slin since our native format has changed to gsm

Reading around, I understood that I would have to add `allow=slin' to
iax.conf, but this hasn't changed anything. The dis/allow part of my
iax.conf is:

[general]
...
disallow=all
allow=gsm
allow=slin
...
[1002]
...
disallow=all
allow=gsm
allow=slin
...

But this didn't change anything.
Then, I was told that I should comment the `allow=gms' line. But this 
made things worse. Now, when I dial asterisk I get the following error:

2005-08-26 07:50:44 NOTICE[31232]: chan_iax2.c:5783 socket_read: 
Rejected connect attempt from 213.210.63.73, requested/capability 
0x8/0xff0f incompatible  with our capability 0xf840.

I don't know much of how codecs work or how to configure asterisk, so 
please help


Thank You,
Daniel
