[Asterisk-Users] SIP UDP ports on firewal to open

[Steve Radich]

I notice most things say to open ports 10000-20000 for UDP for SIP,
however from time to time this range isn't where Asterisk is opening the
ports:

We're at xxx.xxx.xxx.xxx port 8542
Answering with capability 0x2(GSM)
Answering with capability 0x4(ULAW)
Answering with capability 0x8(ALAW)

This call has no audio, presumably because port 8542 is firewalled in
the iptables on the server.

Is there somewhere I'm missing to port a port range in sip.conf
(shouldn't there be if there isn't?).
