Hello,
We are looking for PSTN termination providers located in US. We are planning to get both SER and IAX setup on a single machine. The PSTN provider should support GSM codec preferably or at least SIP.
We are primarly interested in US, UK and Australia countries. Yes, there is a tradeoff between quality and price and we wish to find the correct price-quality margin which will suit us. We will be looking in the order of 10k mins/month in next one year, so quality is definitely important.
Please contact me through PM if interested so that we can follow up. Thanks.
