SPA504G displays "Session Progress" instead of "Ringing" on outbound SIP Trunk

[carlwrcase]

Hello everyone,

When making an outbound call on my SPA504G it displays "Session Progress" when it's ringing. This is displayed right after "Calling" (which I'm assuming is a SIP 100 Trying). Is there any way to get a SIP 180 Ringing if the trunk doesn't send it so that the phone will display "Ringing" ?

It's more cosmetic, but some of the people here won't know what "Session Progress" is and will freak out.

Any help is greatly appreciated!

Thanks!

Hi,

Add the following command on your cisco gateway that the SIP trunk is on:

voice service voip

no supplementary-service sip refer

supplementary-service ringback h225-info

redirect ip2ip

dial-peer voice 1 voip

no voice-class sip asserted-id

no voice-class sip early-offer forced

no voice-class sip block 180

voice-class sip block 183

dtmf-relay rtp-nte

sip-ua

disable-early-media 180

set pstn-cause 1 sip-status 503

set pstn-cause 102 sip-status 503

retry invite 2

retry bye 2

retry cancel 2

timers trying 1000

I apologize. I probably should have mentioned that this is on a SIP Asterisk/FreePBX configuration.
