I saw that URL before and cooperated with telco guys but they told me that
problem came from your side. <br>
<br>
I'm testing "Recovery on timer expiry". Didn't see that error from
log after increased interdigit timeouts on my gateway. After that configuration
I faced new logs :(<br>
<br>
Cause i = 0x82FF - Interworking error; unspecified<br>
Cause i = 0x82C1 - Bearer capability not implemented<br>
<br>
Thank you for any helps :)<br>
<br>
I would like to experiencing on VoIP very much indeed.<br>
