[Asterisk-Users] a beginner's SIP question .. (further!)

Hi,
Check the available codecs at the both ends.
Keep in mind that Asterisk can convert only between G.711 and GSM (without any extra codec installed. like G.729).
Keep in mind too that the Microsoft GSM codec (the one used for example in Netmeeting) is not compatible with the one used by Asterisk or other products. like X-Lite software SIP phone.
BR,
Dan

Hi Dave,
If you have registered the SIP phone with Asterisk, then you must have a line like:
exten => 555,1,dial(SIP/723 at 216,52,153.207)
in extensions.conf file
Then call 555 from the SIP phone to access the destination.
BR,
Dan

I have included a dump of the debug info ...
what I am trying to do is route a call from sipphone 217.168.168.49
through asterisk 217.168.168.51 onto a gateway 723 at 216.52.153.207
If i dial direct from the sip phone to the gateway it works fine .. so
I do not think there is any incompatibility there.
Calls don't go through though ...
please help!!!
cheers
Dave

Hi,
Check to have a common set of codecs.
If X-Lite is used and at the other end is a phone without GSM support, then it doesn't work.
Try to disable GSM on the soft phone (if X-Lite).
BR,
Dan

Subject: [Asterisk-Users] a beginner's SIP question ..
I am trying to get asterisk to dial this address :
sip:723 at 216.52.153.207
Using a softphone on my PC (217.168.168.49)
it dials immediately and I get a voice prompt ..
I have configured an extension, 1303 on asterisk,
modifying the demo configuration :
exten => 1303,1,Dial(SIP/723 at 216.52.153.207)
When from my softphone I dial
sip:1303 at 217.168.168.51
on the console I get :
-- Executing Dial("SIP/sipphone-97b6", "SIP/723 at 216.52.153.207") in new stack
-- Called 723 at 216.52.153.207
-- SIP/216.52.153.207-7c3b answered SIP/sipphone-97b6
-- Attempting native bridge of SIP/sipphone-97b6 and SIP/216.52.153.207-7c3b
but on my headset all I get is silence .. the call doesn't drop though.
What am I doing wrong ?
many thanks,
Dave
