If you choose another codec, you could use a HW-based transcoding solution like the Sangoma D100/500, which goes from 30 to 2000 concurrent calls.
According their website, they don't support Speex.

Thanks,  about how many concurrent calls are you able to when transcoding with FS?

Subject: [Freeswitch-users] SIP Phone Integration

Hi guys,

Am new to Freeswitch and am looking for info that can help me develop a web-based SIP Phone

 I am developing a web-based SIP Phone based on PHP/MySQL and OpenSIPS. I have developed the component of the SIP phone responsible for the 3way handshake and SDP offer. 

My challenge is to now integrate the application to a rtp stack which will enable the app to pick up audio and transmit it over the internet. Ultimately I want to connect the app to the PSTN using a media server such as Freeswitch or Asterisk. I want to use the Speex codec. I wanted to know whether Freeswitch has a rtp stack integrated with speex and whether there any tutorials on how integration to a softphone can be done. Any pointers or ideas from you would be very helpful and highly appreaciated.

regards,
James Mbuthia
