I am having quality problems on SIP bound calls made over the Zap channels. All Sip only calls (Cisco phone through Asterisk to another Sip device sound fine).
Our setup looks like this: User --> Executone PBX --> Asterisk Server --> Router --> Internet The user is using a legacy handset that works with the Executone PBX and accesses the server using a button that calls up the trunk group connecting the legacy PBX to the Asterisk server. According to our Executone technician, the T1 card in the legacy PBX does *not* provide timing so I have the Digium T1 card as the primary sync source as follows: --------------------- /etc/zaptel.conf --------------------- span=1,1,0,d4,ami e&m=1-24 Our /etc/asterisk/zapata.conf file looks like this: --------------------- /etc/asterisk/zapata.conf --------------------- [trunkgroups] [channels] musiconhold=default busydetect=1 busycount=7 relaxdtmf=yes callwaiting=yes callwaitingcallerid=yes threewaycalling=yes transfer=yes cancallforward=yes echocancel=yes echocancelwhenbridged=yes callgroup=1 pickupgroup=1 rxgain=-5 txgain=3 immediate=yes signalling=em_w context=zap-incoming group = 1 channel => 1-24 I get static/popping/clicking on all calls made over the incoming Zap channels (that is, the calls originating from the legacy handsets that trunk into the Asterisk server.) I know very little about the Executone PBX we integrate into, it is under support and these types of questions go unanswered with them as it is out of the scope of the support contract. On the Executone console I can see that I am getting several Blue Alarms. There doesn't seem to be any issues on the Asterisk side, no Red/Yellow alarms. Are there any timing settings I can tweak that will improve the call quality? Anyone familiar with the Executone hardware? Any help at all would be appreciated.
