Hosted Softswitch Integration


Hello Everyone,

We are trying to integrate a hosted soft-switch to an Asterisks server and the error received on the Softswitch end is decline 603

The change that we made is to add the Softswitch IP in the SIP configuration file, see below

On the attempt to integrate to the asterisks server nothing is seen in the asterisk log There is something we might not be doing well. can somebody please help.

remote UPDATE command


Hi guys,
I am working on a setup where I have an Asterisk ( with a SIP trunk
to a provider's softswitch(IMS). Trunking works all ok, calling out and
calling in. Except for the remote softswitch(IMS) will send UPDATE
command(according to RFC 3311) and Asterisk does not accept and thus the
call gets dropped. So, is there a work around for this matter? Or any of you had similar
problem, I really appreciate any directions. The interesting part is that, they have an appliance based Asterisk that
works perfectly fine, so I assume…

SS7 + T1


I spoke with the Asterisk Pre-sales team and they said that SS7
support isn't technically supported, but it is there (e.g. talk to the
OS community about this).... so here's my question: I'm trying to interface an Asterisk Softswitch to a Nortel DMS100.
If I get a dual-span card, can I run SS7 signaling over one span, and
a T1 over the other span and have Asterisk link the two (e.g.
caller-ID for the call on the 1st channel comes across the SS7... and
so forth?)?

Failover trunks


Hi All,
Could you please help me with my following Scenario. I have a softswitch where my carriers send calls from International to my country for local termination. I route these calls to my Asterisk 1.8 which has a number of registered trunks from our SIP Provider. Please guide me how should I configure extensions.conf for calls to be sent to the next available trunk.
Please help.
