no telephony possible after update to core update 156
i have a fritzbox before and a snom ip dect station behind my ipfire. the fritzbox is the sip server for the dect station. after update to core update 156 no telephony is possible. an outside caller hears the ring tone, but it doesn’t ring. an inside caller hears nothing.

does anyone know a solutio…
you have to forward the sip and rtp ports of the snom. (before the update this was done by a sip application layer gateway, but we had to remove this because it breaks security.)

last autumn, we learned about …
well, i raised an issue with id support whom escalated it with engineering or something and it's now working. they did say they'd text me updates and haven't received anything from them so whether they did anything or whether it just started working.. who knows. 

but yeah, looks like the answer is calling / talking to support. only thing i can think of is to maybe reflash the firmware. hi, i think i was able to isolate the issue to flights dispatched via the simbrief api.

it should be fixed now, let me know if you still have the issue in future flights.

thanks, Please refer to the following FAQ regarding your phone's unlocking :

Regards after some playing around i managed to fix this problem. the issue appears to be a forwarding priority problem. there are 4 types of call forwarding which are supported by at&t and most devices, they are: unconditional call forwardingforward on busyforward on unansweredforward on unreachable according to some earlier posts in other threads on this forum it is currently impossible to set anything other than unconditional yourself (even for unconditional i'm not sure, although it appears to work), apparently at&t disabled this some time ago citing security concerns. so, in order to set the others, you need to call 611 and ask at&t to do it for you. so, to the issue. in my case (and i believe in most cases), the default call forwarding number for all of the various types of call forwarding is the voicemail number for at&t (starts with 415 area code). what appears to happen if you try to set unconditional call forwarding yourself is that it appears to have worked, but when someone makes a call to the number, at&t defines the phone to be unreachable, so, instead of forwarding to the unconditional call forwarding number, it forward directly to the unreachable call forwarding number, which is set to the voice-mail number, and the caller is directed immediately to voice-mail. the way to fix this is to change the call forwarding for 'unreachable', but as i mentioned earlier, you can't do this yourself; i have tried with both the phone settings and the mmi number (which btw is very hard to find), both return some kind of error indicating that it cannot be done. so, you need to call at&t and tell them, very specifically, that you would like to set *only* your 'forward on unreachable' to the number that you actually want to forward to. now, when the caller calls the number, if you have set unconditional call forwarding, or you turn off your phone, or you set it to airplane mode, or you take the sim out and go to another country, your calls will be correctly forwarded directly to the 'forward on unreachable' number, which is correctly set. i have done this, and it works perfectly...it's easy to test, you just need to put your phone in airplane mode.  to any google voice users, i have set mine to a google voice number, and it works perfectly. now, if i have wifi access in another country, or i put another sim in my phone that has internet, i will be able to answer calls that come in to my at&t wireless number on my google voice number. beware that the level 1 staff at the 611 line are completely clueless about this and they will try to send you a link to the set of instructions to do it yourself...they don't work; you need to insist that you want them to do it, and try to talk to one of the wireless experts who can actually set the correct call forwarding at their end. be prepared with your imei number, they asked me for it for both lines. Hi,
