Hello to the FreeSWITCH users, I'm experiencing problems registering an Aastra 6731i phone to FreeSWITCH. The registration process itself works fine, but the phone never re-registers to FS after the expiration time specified in the expires paramater set in the Contact SIP Header Field. And therefore becomes unreachable from FS after some time. The phone seems to be buggy because it simply ignores the value given in the expires parameter. Testing with Asterisk, the phone remains accessible, because Asterisk adds an Expires HF in addition to the expires param in the Contact HF. Did anyone observed what's described here? I've tested several Aastra firmwares with the same result. I have also tried to set the registration expiration time on the phone itself without success. I believe I can cope with this situation by adding an Expires HF from the (SIP Express Router) proxy that stays between the phone and FS, but I'm sure there's a simpler way to get a proper registation process. I'm using FreeSWITCH 1.0.6 (that comes along with the Blue.box GUI). Kind regards, Philippe
