<br><div class="gmail_quote">Hi All,<br><br>I am facing a strange problem while using music on hold on SS7 during dialing. <br><br>We did the development and testing using SIP and everything was working fine, when we started deployment on the production machine with SS7 E1s on a GSM carrier, we got into this issue.<br>
<br>Here is my dial plan snippet:<br><br>exten => 345,1,Progress()<br>exten => 345,n,Set(CALLERPRES()=allowed_passed_screen)<br>exten => 345,n,Set(CHANNEL(musicclass)=default)<br>exten => 345,n,Dial(ss7/ls1/03452129134,,m)<br>
<br><br>I get the following in the log please note that the "Stopped" line appears immediately after the "Started" line (phone numbers removed):<br><br> -- Recv IAM CIC=1253 ANI=... DNI=... RNI= redirect=no/0 complete=1<br>
-- Executing [345@default:1] Progress("SS7/ls1/1253", "") in new stack<br> -- Executing [345@default:2] Set("SS7/ls1/1253", "CALLERPRES()=allowed_passed_<div>screen") in new stack<br>
-- Executing [345@default:3] Set("SS7/ls1/1253", "CHANNEL(musicclass)=default") in new stack<br> -- Executing [345@default:4] Dial("SS7/ls1/1253", "ss7/ls1/...,,m") in new stack<br>
-- Sent IAM CIC=1418 ANI=... DNI=... RNI=<br> -- Called ls1/...<br> -- Started music on hold, class 'default', on SS7/ls1/1253<br> -- Stopped music on hold on SS7/ls1/1253<br><font color="#888888"><br>
</font></div>However, if I use: MusicOnHold(default) in the dial plan, I can hear the music placed in moh.<br><br>exten => 345,n,MusicOnHold()<br><br>We are using the following components:<br><br>libpri : 1.4.10.2<br>
