[Asterisk-Users] No audio in either direction, sip channels hanging, asterisk will not shut down.
Hi all,
I have been asked to look into using asterisk as part of our setup.
The eventual goal is to replace as many parts of the existing setup as
possible, but in the interim, I just have to make it bolt on and work
with all existing parts.
My current setup is as follows:
Cisco 7940
(ext 2000)
|
v
Asterisk -> Snom SIP proxy(v2.22) -> Vega100 PSTN gw -> Index PBX
| | |
v v v
Cisco 7940 Cisco 7940 Phone
(ext 2001) (ext 7038) (ext. 3046)
All the sip connections are working fine, i.e. I can call between
extensions 2000, 2001, 7038 on the above diagram with no problems.
Also the connection from the Snom Proxy to the PBX works fine.
(7038->3046) and vice versa.
The problem I have is that I can ring from the phones on asterisk to the
phones on the PBX, but I have no audio in either direction.
After attempting this the call seems to not terminate properly, the sip
phone involved refuses to cooperate, and asterisk refuses to shut down.
If I issue "stop now", the CLI just hangs indefinitely. "sip show
channels" reports 2 active channels ( between the phones involved ).
Firstly, is there any way I can rescue asterisk without doing a "killall
-9 asterisk", which is how I am currently dealing with this. ( Also, how
does one determine the <channel> parameter to be used with "soft
hangup" ?)
Secondly, I have attached the trace from the CLI with "sip debug"
turned
on. Does this shed any light on what is causing the problem ?
I appreciate this is an involved query, but I have been poring over the
sip debug trace for a whole day now, and it still makes no sense to me.
Any help would be greatly appreciated.
Regards,
Rhys.
