Here is a very strange problem I’m running into with
all of the IAXy’s we’re testing in regards to ringback when placing
an outgoing call…. First, let me describe the setup…. We have a
production Asterisk 1.0.9 box running that uses SIP trunks to connect to various
Cisco voice gateways. Those Cisco gateways then connect to internal
switches (DMS-100’s) via PRI’s. The “analog”
phone switch it connects to uses 5 digit dialing for internal numbers, and 7 or
10 digit dialing for external and LD numbers. Therefore, when I am
dialing from an IAXy through Asterisk to another analog internal extension, I
am just using 6 digits. I have the dial plan setup to match the internal
extensions as their 10, 7, or 5 digit numbers. If, for some reason, the
person dials the full 7 or 10 digits to dial an internal neighbor, it just
strips the unnecessary numbers and sends it to the trunk. Now here’s the problem with the IAXy…. If
I dial an internal extension from the IAXy as XXXXX (5 digit), the destination
rings and the call completes, but I DO NOT hear ringback tone. If I dial
an internal extensions as XXX-XXXX (7 digit) or XXX-XXX-XXXXX (10 digit), the
call completes and I DO get ringback tone. I’ve looked in the logs, and the dial plan is working
correctly, whether the person dials 5, 7 or 10 digits, asterisk is only sending
5 digits to the trunk to complete the call. Also, I thought it may be the
IAX driver causing problems, but we have a number of Chinese made phones with
ATCOM chips that use the IAX protocol, none of which are experiencing the same
ringback tone issues. I’ve also tried the “beta”
version of the IAXy firmware… Does this mean the IAXy has some sort of dial plan that
controls when it creates ringback tone? Any help would be appreciated… Thanks, Scott Miller |
