Please email to me( Note that you need to copy the link of this forum, so I can know the problem.

I have the same problem (using 3CX) and a T58V:
If I reduce the Codecs to alaw, and ulaw, the packet size is 1508. That works, but, if I add G729, G722, and more, the packet size goes up to 1538.
Normally that is not of a big problem, but, depending on the receiving party or in my case I have a remote phone connected through a VPN tunnel. I simply cannot start a call.
A good SBC will most likely filter the header, and will remove unnecessary talk. But in my case this is a remote location with only one phone.

It the email address still correct?
