[Asterisk-Users] Problem with PRI and Ericsson AXE 10

Wed Oct 12 09:44:17 MST 2005

Hi everyone,

I have a PRI conection on an * system running Asterisk 1.0.9, libpri 1.0.9 and zaptel 1.0.9.2 connected to an AXE 10 (APZ 21220 System 64) in the network side. I know the system and the wildcard I´m using are ok because I´ve used them before with other PRI connections (to a Siemens EWSD) without any problem.

First the PRI didn´t work (I got the TE110P alarmed with red). After troubleshooting with the Telco, they told me to disable crc4 and then I got the green ligth, the 30 B channels cleared, and I was able to dialout to the PSTN but only until the channels restart, because this made the call to hangup. Besides, when I make a call towards the system, I got a busy tone from the PSTN and no activity on the CLI.

The Telco has called to the system too and they say they got a "connection reject" even they "see" the channels available.

For troubleshooting porpouses, they have enabled the most simple configuration of PBX in the network side of the PRI (no DIDs, 30 B channels and one header).

These are the messages that I got in the CLI:

The system seems to have problems to get the D channel at first, then it synchronizes, and then it loses the sync again. I´ve changed the timing parameter in zaptel.conf from 0, to 1 and 2; and set/unset the yellow parameter in the span config line, without luck.

I was getting messages like "051010-082926 WARNING[3092]: chan_zap.c:1261 zt_disable_ec: Unable to disable echo cancellation on channel 2
" too, but after I disable echo cancellation, they dissapeared.

I´ve tried changing the overlapdial parameter to yes, the pridialplan to local and unknown, and the priindication to outoband but the system still has the same behaviour: dialout works until the channels get cleared and there are NO incoming calls working. I´ve double checked my context for incoming calls, and modified many parameters in zapata.conf without success.

This is my zaptel.conf::

span=1,0,0,ccs,hdb3
bchan=1-15
bchan=17-31
dchan=16

loadzone=us
defaultzone=us

----

And my zapata.conf:

Any help on what might me wrong, would be appreciated.

Regards,

Juan Manuel
