[asterisk-users] Extensions busy/congested and "circuit-busy"

[Guy M Guyadeen]

Thank you for your response!
That was exactly the problem - the 841s use a deprecated identifier  
for G.726. Behavior and solution is described here:

http://www.voip-info.org/wiki/view/Sipura+SPA-1001
1) To use G726 with asterisk 1.2.6 or later you must edit the rtp.c  
and either dfine USE_DEPRECATED_G726=1 or remove the #ifdef  
USE_DEPRECATED_G726 statement. If you do not do this you will be able  
to place calls using the SPA but not receive calls. This is because  
the SPA identifies the G726 codec using a deprecated paylode type.

I did that, make, make install, asterisk -rx "restart gracefully",  
and viola! it works.

THANK YOU!

Guy
