Vodia PBX Posted October 9, 2013 Report Share Posted October 9, 2013 There is a problem with the snom phones. The synchronization of the DND and redirection state between the PBX and the phones make the phone send a redirection, although this must not be done on the phone (this is done on the PBX). Yealink, Grandstream, Polycom work this way. There is a trouble ticket open with snom for a couple of moons and AFAIK it will be included in the next firmware release. If you want to test a beta firmware or get the release date, please contact snom for details. Quote Link to comment Share on other sites More sharing options...
gifti Posted October 10, 2013 Author Report Share Posted October 10, 2013 Its is only when you call "remote" over the website and "call forward no answer xx seconds" is enabled. What is the difference to a normal "phone initiated" call? The first INVITE starts from the PBX and shoud not allow refer, doesn't it? INVITE sip:26@192.168.0.210:1752;transport=tcp;line=ya734foz SIP/2.0 Via: SIP/2.0/TCP 192.168.0.200:5060;branch=z9hG4bK-66360e544144f248b39928874c97d11a;rport From: <sip:26@pbx.ggizef.lokal>;tag=1845693600 To: <sip:xxxxxxxxxx@pbx.ggizef.lokal> Call-ID: 1b8dcdd5@pbx CSeq: 14894 INVITE Max-Forwards: 70 Contact: <sip:26@192.168.0.200:5060;transport=tcp> Supported: 100rel, replaces, norefersub Allow-Events: refer Allow: INVITE, ACK, CANCEL, BYE, REFER, PRACK, INFO, UPDATE Accept: application/sdp User-Agent: snomONE/5.1.1 Call-Info: <sip:26@pbx.ggizef.lokal>;answer-after=0 Content-Type: application/sdp Content-Length: 324 But I'am not a SIP expert. It isn't a serious error. Workaround -> disable CFNA before call remote. I wait for the new release . Quote Link to comment Share on other sites More sharing options...
