[Asterisk-Users] [perhpas OT] asterisk holding rtp ports open with natted spa-3000

Thu, 18 Nov 2004 19:56:28 -0800

i'm running asterisk ( Asterisk CVS-v1-0-11/15/04-21:24:51 ) on a public IP address and am accessing it with natted x-lite and spa-3000 clients. the xten client runs perfectly and i can also make and receive calls with the spa-3000 with no issues, so both appear to be configured correctly; however with the spa-3000, asterisk keeps opening rtp ports until there are none left which leads to Bad Things [1]. since the xten client doesn't exibit this behavior, and both clients can make and receive calls, i'm probably way off topic for this group, but i thought i'd lob this out and see if anyone had any helpful suggestions or had seen anything similar. the only reason i feel i have a valid reason to post this to an asterisk group is that the spa-3000 is configured to have a maximum of 4 rtp ports open, so it seems wierd that asterisk would be opening/keep open a large number of ports [ e.g. 2, which shows just a small sample of open rtp ports]

to my relatively untrained eye, the sip debug log looks good [3], except that there is a lot more message traffic as compared to when only the xlite client is connected; i was able to moderate the behavior slightly by altering the "register expires" parameter based on a suggestion from a voxilla forum thread [4], but the problem still persists. the only other circumstantial evidence that i have is that asterisk keeps telling me that the Line 1 peer becomes unavailable and available over and over again [5], which seems to be associated with the run-up on open RTP ports.

again - apologies if this is off topic, but i'm pretty much at wits end with this.
