Thank you all for your comments.

After having researched documents and history from both iptel and OpenSER,
I could not resist a feeling that iptel is somewhat lagging in their
intension to go forward with SER to the direction that it had headed to.

Naturally by huge changes in key members and contributors, may it lead to
changes in business and philosophy, as Daniel mentioned more factually.

We decided to switch to OpenSER while we are in testing phase and we have
two key questions that we'd like to here from the experts.

1. Is there any comtatibility issues out there between SER and OpenSER
   mixed infrastructure; due to differences in functionality between SER
   and OpenSER?

2. Hardware and OS question regarding OpenSER;
   Is there any known obstacles over Fedora Core;  2.6.12-1.1387_FC4smp
   SMP version running on dual Athlon 64?

Again, thank you all in advance.
