I have several Polycom IP550 phones running UC 4.0.3, connected to Asterisk 1.8.

Setting forwarding for “Always” works as expected; the phone issues a 302 Moved Temporarily, and Asterisk shifts the call to the new location.

Setting forwarding to “No Answer” means a 302 never gets issued. It just rings and eventually goes to voicemail. Watching with Wireshark, I never see a 302 SIP message issued. I can’t find anything in the phone settings that look like it would disable this.

Anyone else with a Polycom set that sees this, or does not see this and has “forward no answer” working?

  • I have Polycom IP550. The “Forward” “No Answer” is working fine when enabled. I was looking at the sip.cfg but don’t know exactly what to look for, can you give me a hint to where would i find that option?

    Thanks,

  • I think it’s ‘divert.noanswer’, found in site.cfg, or at least that’s where I have it. It’s set to enabled and it still doesn’t work. Out of curiosity, do you have reg.1.fwd.noanswer.status set anywhere?
