They have a problem with g722 and early media. Either turn off g722 on the phone or actually answer the call prior to bridging. I have a ticket open with Siemens on this with traces but have heard nothing recently from them. I have the following in my dialplan towards the top to unconditionally "answer" if the endpoint is a A580ip: <extension name="fix siemens" continue="true"> <condition field="${sip_user_agent}" expression="^A580 IP"> <action application="log" data="CRIT early answer for siemens"/> <action application="answer"/> </condition> </extension> On Fri, Jul 9, 2010 at 11:31 AM, Nick G <nick@hkcradio.com> wrote:
Greetings. I have a bit of a problem with placing outgoing calls with my Siemens on my freeswitch PBX, which seems to have to do with the way it handles sending a ring signal to someone on the call. Instead of the method used by other PBX's, it seems to send audio back, rather than being content to let my sip device take care of sending me the ring signal. Consequently, it has a hard time negotiating media when someone actually picks up the call. Can I fix this? If so, how? Thanks, Nick
