Hi All,
I'm a problem using conference with calls between an internal 7931 IP Phone and two external GSM Phone.
To call gsm phones I use an IP GSM gateway (Quescom) with four simultaneous channels (4 GSM SIM)
Normally I haven't any problems when 1, 2, 3 or 4 users call external consumers using GSM gateway.
Now, if I try to start a conference: first call to outgoing user on GSM (for example: 03381234567), next press CONF on IPPhone display, next I try to digit
second GSM phone number, but on phone display appears "impossible to complete conference".
Note: for emergency calls on GSM numbers, (GSM gateway out of service or bad signal cell, etc), I have attivated to force outgoing calls on GSM numbers,
a numbers sequence to digit before to digit GSM number = 0 + 9 + GSM phone number. This mode enable user to call a GSM number using ISDN channels.
Using this method the conference between two external numbers and one internal works correctly, as between tree internal numbers too.
In attach the configuration on the router ISR 2821.
Please could you help me to solve this problem?
Thank you for best support
Kind Regards
Tonino
