Hi Mike ,
Nice to meet you .I know you worked with sathis, siva some time before.
I have been in line with Voip from 1998 and may be i am new with you.
For your information we are not based in India ,but we are based on SAARC and Asia pacific.
My experience with VOIP is seven years.
You might know that We have been providing support for Quintum call shop,calling card,corporate set up all over the globe for FREE.
I started with Cisco systems and then have experience in say Quintum ,welltech ,audiocodes ,Level one products.
Neverthless all the VOIP appliance work with same protocols and principles so no need to have experience in particular product for many years.
