Hi there.
I have sent this message once but i will try one more time. I am testing a scenario when tha UA is behind the nat and it is called from pstn through a cisco pstn access gateway, (from a carrier ); The UA is behind the nat (a Linksys route or a Linux nat so far only these have been tested). ser /mediaproxy | ------------------------------- | nat/ua cisco/pstn gate
So far i have tested calls from pstn to DIN assigned to the ua behind the nat. When i use a grand stream/bt100 the media is not comming and going to the UA . during the dilaog i run a trafshow utility and session tool of mediaproxy and it shows that media is comming ftom cisco/pstn but nothing gets out and nothing commes from bt100/nat. In the same scenario if i use xpro it works , media gets through.. Wen i call from an bt100 behind the nat to another bt100 behind the nat it works .. the media gets through I am beating my head of walls and cannot figure out for more then 1 week. But i am getting experience day by day. I some o one with more experinece would point what is wrong i would apprechiate. Thanks. PS: os is fc2/Linux ast 2.6.5-1.358smp #1 SMP

The bt100 i tryed latest and previos firmware the same result. Thanks again Decebal
It might not be a SER problem.
I'm unable to make a Grandstream HT-486 talk to a Cisco Access Server with IOS 12.2. Same with a ZyXEL P2000W (aka WiFI Phone or BCM-600, whixh are all the same). But it does work with an ATA-186.
SER just rewrites what it needs to be changed and forwards the rest of the packet virtually untouched. a Cisco gateway needs two TCP packets to send the whole invite, with all the additional information, and the Grandstream doesn't understand part of it.
