TELKOM SIP TRUNK - FREEPBX

Hi,

I am looking for the correct settings to use with FreePBX on Telkom SIP Trunks.

I have managed to set everything up to the point where I can receive calls via the Telkom SIP line but can't make any calls.

The correct settings is required for outgoing calls.

Thanks,

OK, I have found the problem. Some of our SIP Suppliers require a "Asterisk Trunk Dial Option" be set to trwW.

Telkom requires it to be twW for anyone having issues with dialling out.

Outgoing:

Type=peer
qualify=yes
Insecure=port,invite
Host=[Telkom Hostname]
dtmfmode=rfc2833
Disallow=all
context=from-trunk
Allow=g729:60,alaw:20 (Telkom only except calls at ptime 60ms for G729 & ptime 20ms for alaw)
secret=Your password you have set on the My Telkom Web page under SIP Trunks
username=2711xxxxxxx
Fromdomain=[Your Domain Name] (As supplied by Telkom)

 

Incoming:

Qualify=yes
Permit=[Telkom Hostname]
secret=Your password you have set on the My Telkom Web page under SIP Trunks
Insecure=very
Fromuser=2711xxxxxxx
Fromdomain=[Your Domain Name] (As supplied by Telkom)
dtmfmode=rfc2833
Disallow=all
context=from-trunk
Allow=g729,alaw (You need to be able to except any ptime ms Telkom send you)

 

Register String:

2711xxxxxxx@[Your Domain Name]:[password]@[Telkom Hostname]/2711xxxxxxx

 

Hope this will help someone else looking for the details to setup a Telkom Trunk in FreePBX.

Re: TELKOM SIP TRUNK - FREEPBX

Hi All,

 

I have been struggling to connect my FreePBX with Telkom.

 

Besides them having to clear their block list every time I try, they say my register string is incorrect.

 

Please clarify that the domain name is what they have in their portal, in the format 2731XXXX.zzz.stdsiptrunk.telkom, and that the telkom hostname is dng1.er1.stdstrunk.be.telkomvoip.co.za

 

if this is all correct, I have the correct register string. 

 

Does it make a difference if my PBX is behind NAT? Will Telkom need to make a change?

 

Thanks in Advance for the replies.
