Re: [Linphone-developers] Issue PSTN Calls with Blackberry Linphone

Hi,

i had already did the changes in sip.conf. but We will get issue when we send this call to the termination provider they don't accept as because amr-nb codec is not there on the termination side.

Please help me.

Assuming you install the amr-nb codec in asterisk 1.4, you can see the codecs and whether asterisk can convert between them with:

core show translation

at the asterisk command-line. After confirming that there is a translation path between amr and for example ulaw, you

disallow=all
allow=ulaw

in the peer definition for your provider(s), and:

disallow=ulaw
allow=amr-nb

For the user definition of the bb clients. I am not sure the codec is called amr-nb, it was a guess.

Also, you disable all the options that asterisk has of renegotiating a direct audio path between the clients and provider, so it can do the conversion (see canreinvite and similar options in sip.conf).

Cheers,
Iordan

Hi,

I will install AMR-NB codec on my server. after that i will get issue on termination side as now a days no termination provider is supporting ABR-NB codec so is there any way we convert AMR-NB to other codec like GSM, g721 or any other codec.

Thanks
