what SIP methods are supported?


The following (RFC 3261 - SIP: Session Initiation Protocol) requests are supported 'invite/ack/bye/cancel'.

The 'options' and 'register' requests are not supported.

RFC 3515 - The SIP 'Refer' Method (call transfer) is supported.

RFC 3263 - SIP: Locating SIP Servers is not fully supported. Our system does resolve SRV DNS records when sending calls but will only use the first SRV entry.
