It is strange behavior. If all necessary codecs are enabled, then
negotiation should traverse all codecs until a match is found, but
it seems that in your case, it stops with the first. As a way of
isolating the issue, try routing calls direct to a call group and
have both clients make calls. If you can recieve calls from both,
then the issue is probably in the agent. I've never played with call
centre before so unfortunately, I've got no idea what might be the
issue there.<br>

inbound_late_negotiation should *just work* without setting the
other options, try removing them and leaving
inbound_late_negotiation set to true.<br>

ya, I know, this was the default setting in my env, it didn't
work.<br>

If you are using this option, set it to false in all sip
profiles. Of course, any proxy_media or bypass_media options
should also be set to false.<br>

I set inbound_zrtp_passthru=false in all sip profiles, still
didn't work.<br>

Yes, it is the last resort. <br>
Do these settings about codec negotiation not take effect when it
comes to callcenter application?<br>
<br>
Thanks.<br>

Am I right in assuming that inbound calls are coming from

<font face="Arial">Hi,<br>
<br>
I have two clients using different codecs.<br>
Client A: PCMA, H264<br>
Client B: G729, H264<br>
Agent: PCMA,G729,H264<br>
FS:PCMA,G729,H264<br>
<br>
Now agent could only accept calls of client A but not
from client B. <br>
When I change the codec order of FS to G729,PCMA,H264,
then agent could accept client B but not from client
A.<br>
I have tried these settings below and all in vain.<br>
1) add <action application="set"
data="inherit_codec=true"/> in diaplan
(inbound-late-negotiation is true)<br>
2) add <action application="export"
data="nolocal:absolute_codec_string=G729,H264"/> in
diaplan B.<br>
3) add {absolute_codec_string='G729,H264'} in
callcenter application, syntax error<br>
<br>
Here is the diaplan.<br>
<extension name="Test Call Center"><br>
<condition field="destination_number"
expression="^555$"><br>
<action application="sleep"
data="1000"/><br>
<action application="callcenter"
data="555@default"/><br>
</condition><br>
</extension><br>
<br>
How can I configure to accept both clients?<br>
Any advice would be appreciated.<br>
<br>
