Hi all,
I have a strange issue, with a some kind complicate architecture...
A router of our internet provider is in front of another bintec rs353j
router, at which my freepbx installation is located. However, NAT etc.
seems to work fine.
BUT: Something is not working...:
When registering my sip-trunk towards my provider (3 different
providers, all behave comparable), everything works at first. Calls
are possible. But after some time, when the next REGISTER happens, the
answer of my provider is sent towards the wrong port. My freePBX
listens on 55060, where the first registration request are answered as
they should. in the second registration request wrong ports are used.
besides this, Header "Expires" is set to "0" and no "Allows" are
listed...
[...]
Any suggestions how to fix this? Or at least any idea what causes this?
regards,
andre
