Hello, I think I have encountered an odd bug in Siemens C460 IP/dect handsets, which is a bit annoying, and I'm not (yet) sure how to get round it without lots of hacks.
Basically, on all external incoming calls, we set: exten => s,n,SIPAddHeader(Alert-Info: Bellcore-dr2) This causes handsets (i.e. Cisco 7960 / Grandstream / aastra) to set a different ring cadence so to differentiate between external and internal calls. Other handsets that do not support Alert-Info: just ignore the presence of this header. When this header is set in a call to the C460 IP, it does not alert, in fact it does not respond to any INVITE requests; asterisk just retries the requests a few times and then gives up. Anyone able to reproduce? I have firmware version 010700000000 / 041.00 I suppose as a workaround I could add an astDB entry for these extensions, and a bit of logic in the dialplan to tell asterisk not to add the header for extensions that have that flag set.
