When I attempt to call using spark, I receive an error “Invalid number”. In Asterisk log: sip_inv.c .Error parsing/validating SDP body: Unknown error 220030
In Openfire web interface SIP Phone status in mappings is registered and if I trying call from another sip phone, spark receive call, but immediately terminates the call. In Asterisk log get same error.
this is a codec issue or something thats coming from the sip phone plugin of spark. you can try disabling all but alaw/ulaw. howerver, that is the less of your problems. the sip phone plugin needs a lot of work, and there are some terrible audio issues that have yet to be addressed.
