Summary: Yesterday I inadvertently unplugged my Grandstream phone. I might add I did a rebuild of my s/w from CVS at the same time. Since then, the Budgetone seems to talk SIP just fine, but the RTP being sent to it by asterisk "doesn't make any sound."
It was suggested I do a factory reset of the phone, which I did.
I have traced until I'm blue in the face--the SIP part looks normal and the asterisk server sends its audio stream just like it's supposed to, but I can't hear a thing. Calls to NuFone and other providers proceed normally until the start of the RTP stream, then stop cold.
I am suspecting codec compatibility, but ain't smart enough to figure out from the attached trace whether my hunch might be correct.
Could someone take a quick gander at the RTP negotiation in this trace and see if there is a smoking gun--I dialed "8" on the Budgetone (192.168.1.21) to get voicemail on the asterisk box (192.168.1.10).
Thanks.
B.
