Siemens responded to my initial query yesterday with a rather unhelpful: 'It is an asterisk issue, and we don't support asterisk' type response. But they did point me to a link: http://www.voip-info.org/wiki/view/Siemens+Gigaset+C450IP On this page, somebody suggests a workaround: "EDIT: Actually, there is a way to have alert_info work with other phones and still have the C450IP work with the same configuration. Even though the C450IP will not have a distinctive ring. Just make sure that you set your alert_info variable in the following way: exten => s,1,SetVar(_ALERT_INFO=<something>). Note the < and > in the command. The C450IP will still ring, and at least the other phones I have tried with will accept that syntax." I have not tried this so I don't know if it works yet, as not sure yet if it will break other things or which is valid syntax for the SIP header. I have a sneaky feeling that this method of "SetVar(_ALERT_INFO" is replaced with SIPAddHeader() only in asterisk 1.4 anyway? My experience with Siemens in the past is that they will probably not fix a bug like this unless you are negotiating a large contract and it becomes a critical item for them to address in order for them to get the business. Individual joe-users usually don't count for much. Otherwise they just seem to stall and stall, and then eventually phase out the particular model of handset and replace it with a completely different model, usually with many of the same bugs and foibles. They *do* seem to have addressed one pet hate I had of all the Siemens DECT phones though, in that finally the Red and Green call answer/hangup buttons are positioned with the green button on the left, and the red button on the right, and not the other way round, like pretty much every other mobile/cordless handset on the planet. (the times I went from Nokia handset to Siemens handset and out of habit rejected calls instead of answering them!!)
