Hi,

I am having an issue with call transfer, it seem when I receive an incoming call and the receptionist transfer it to an extension, the caller hears the person, but the person at the ext doesn't hear them.

I am using a m8l pbx and yealink T22 and T 28, I check in the codecs with make secure etcetc and the code in the phones are PCMU,PCMA, G729, G722.
In the pbx this is .
711u (PCM audio coding standard, 8 kHz sample rate, 8 bits, 64 kbit/s data rate) (preferred) Enabled
G.711a (PCM audio coding standard, 8 kHz sample rate, 8 bits, 64 kbit/s data rate) Enabled
G.729a (CS-ACELP speech coding at 8 kbit/s rate)

Does any one have any ideas, I need to solve this quickly.

Krs,
