Do you have any firewalls in the middle that may be blocking ports on the pbx?

it sounds like your having a one-way-audio issue. Can you provide with a sip-trace from the pbx?

 

 

follow these instruction so you capture the trace.

I ve got one way audio only when a second call arived when it stop ringin everything is ok.

 

My config is snom one blue (192.168.1.200) + 30 snom phones (300 , 821 and M9 a lot of pb with M9) network 192.168.1.0 + one Patton 4638 (192.168.1.201)

 

Tomorrow i capture the trace

I ve done some more test and the result is :

with SNOM M9 (45 ext) no pb

with snom 320(40 ext) no pb

with snom 870 or 821(41 ext) pb when a second call ring when i m on line the first peoople who call me don't hear me when the 2 call stop ringing it's ok again

 

the problem is also with a client who have 4.3 and patton 4638 or in our office with 4.5 + SIP OVH TRUNK the codec who is used is G711a

 

thanks

Based on your testing looks more like a phone issue. But we will test it here before escalating to the phone forum (forum.snom.com)

 

Another test if the first call is an internal call no problem , only if the first and second call come from outside
