Appendix 8 – TEL URI handling for Cisco VCS
to OCS calls
If an endpoint wants to dial a telephone number rather than selecting a user from a directory, the
Cisco VCS Control must format the telephone number appropriately for OCS to be able to look it up.
OCS expects to see telephone numbers (known as TEL: URIs) in the form:
+<country code><full dialed number>
Cisco VCS Control can use transforms to appropriately format the telephone numbers. These
transforms can either be implemented globally using VCS Configuration > Transforms or just for the
OCS Neighbor zone by configuring the transform in the appropriate Search rules.
For example, for 4 digit extension number dialing to be expanded to a full telephone number for a
company in Bracknell UK whose telephone number is 781xxx, an extension number 1008 would need
to be expanded to [phone].
For a non OCS Relay system this can be implemented as follows:
Priority
80
(match in preference to the no transform needed rule - 80 is higher
priority than 100)
Source Any
Mode AliasPatternMatch
Pattern type Regex
Pattern string
(1…)(@vcs.domain)?(.*)
(@vcs.domain will exist in SIP originated calls but not in H.323
originated calls)
Patter behavior Replace
Replace string
[phone]\1;@test-customer.com;user=phone\3
On successful match Continue
Target Zone OCS
