Is TCP support under consideration?

extra notes:

I tried decreasing packet size by only adding 1 video 1 audio codec.
Also disabled all QoS options.
Unfortunately packet size is still big.

TCP is not supported on my proxy server.

Hi,

Any news on this ?

Btw, I am willing to change my 3g interface MTU settings. But  I don't know how.
How can I see the current mtu setting and change it ?

maybe we could have better chance in Imsdroid 2.
But is there a compiled version of Imsdroid 2 with codec g729 ?

I also found this problem! the invite message is too long to transfer to ims 
client is 3G network. you can solve this problem by reduce the length of invite 
packets through removing of the useless infomation added by imsdroid. The other 
resolution is using sip message compression to make message not exceed MTU or 
using the two methos at the same time. I have tried and successed, good luck to 
you!

hi qiufei230

can you guide us how did you reduce the length of the INVITE message.
As we dont have access to the ngn stack related code we are unable to reduce 
the INVITE length for imsdroid.
Will appreciate any help on this
